+.In libelftc.h
+.Ft int
+.Fo elftc_demangle
+.Fa "const char *encodedname"
+.Fa "char *buffer"
+.Fa "size_t bufsize"
+.Fa "unsigned int flags"
+.Fc
+.Sh DESCRIPTION
+Function
+.Fn elftc_demangle
+decodes a symbol name encoded according to the type encoding rules
+for the C++ language and returns a string denoting an equivalent
+C++ prototype.
+.Pp
+Argument
+.Ar encodedname
+specifies the encoded symbol name.
+Argument
+.Ar buffer
+denotes a programmer-specified area to place the prototype string in.
+Argument
+.Ar bufsize
+specifies the size of the programmer-specified area.
+Argument
+.Ar flags
+specifies the encoding style in use for argument
+.Ar encodedname .
+Supported encoding styles are:
+.Bl -tag -width ".Dv ELFTC_DEM_GNU3"
+.It Dv ELFTC_DEM_ARM
+The encoding style used by compilers adhering to the conventions of the
+C++ Annotated Reference Manual.
+.It Dv ELFTC_DEM_GNU2
+The encoding style by GNU C++ version 2.
+.It Dv ELFTC_DEM_GNU3
+The encoding style by GNU C++ version 3 and later.
+.El
+.Pp
+Argument
+.Ar flags
+may be zero, in which case the function will attempt to guess the
+encoding scheme from the contents of
+.Ar encodedname .
+.Sh RETURN VALUE
+Function
+.Fn elftc_demangle
+returns 0 on success.
+In case of an error it returns -1 and sets the
+.Va errno
+variable.
+.Sh EXAMPLES
+To decode a name that uses an unknown encoding style use:
+.Bd -literal -offset indent
+char buffer[1024];
+const char *funcname;
+
+funcname = ...; /* points to string to be demangled */
+if (elftc_demangle(funcname, buffer, sizeof(buffer), 0) == 0)
+	printf("Demangled name: %\\n", buffer);
+else
+	perror("Cannot demangle %s", funcname);
+.Ed
+.Sh ERRORS
+Function
+.Fn elftc_demangle
+may fail with the following errors:
+.Bl -tag -width ".Bq Er ENAMETOOLONG"
+.It Bq Er EINVAL
+Argument
+.Ar encodedname
+was not a valid encoded name.
+.It Bq Er ENAMETOOLONG
+The output buffer specified by arguments
+.Ar buffer
+and
+.Ar bufsize
+was too small to hold the decoded function prototype.

+.Sh NAME
+.Nm elftc_set_timestamps
+.Nd set file timestamps
+.Sh LIBRARY
+.Lb libelftc
+.Sh SYNOPSIS
+.In libelftc.h
+.Ft int
+.Fn elftc_set_timestamps "const char *filename" "struct stat *sb"
+.Sh DESCRIPTION
+The
+.Fn elftc_set_timestamps
+function is used to set the access and modified time stamps on a file
+based on the contents of a
+.Vt "struct stat"
+descriptor.
+.Pp
+Argument
+.Ar filename
+names an existing file in the file system.
+.Pp
+Argument
+.Ar sb
+points to structure of type
+.Vt "struct stat"
+populated by a prior call to
+.Xr fstat 2
+or
+.Xr stat 2 .
+.Sh IMPLEMENTATION NOTES
+This function will invoke the high-resolution
+.Xr utimes 2
+system call if the underlying operating system supports it.
+On operating systems lacking support for
+.Xr utimes 2 ,
+the function will use lower resolution
+.Xr utime 2
+system call.
+.Sh EXAMPLES
+To set the access and modified times for a new file to those of an
+existing file, use:
+.Bd -literal -offset indent
+struct stat sb;
+const char *existing_filename, *new_filename;
+
+if (stat(existing_filename, &sb) < 0)
+	err(EXIT_FAILURE, "stat failed");
+
+if (elftc_set_timestamps(new_filename, &sb) < 0)
+	err(EXIT_FAILURE, "timestamps could not be set");
+.Ed
+.Sh SEE ALSO
+.Xr fstat 2 ,
+.Xr stat 2 ,
+.Xr utime 2 ,
+.Xr utimes 2 .

+.Sh DESCRIPTION
+This manual page documents convenience routines for handling ELF
+string tables.
+.Pp
+Function
+.Fn elftc_string_table_create
+creates a new, empty string table.
+The argument
+.Ar sizehint
+provides a hint about the expected number of bytes of string data in
+the table.
+If the argument
+.Ar sizehint
+is zero, an implementation-defined default will be used instead.
+.Pp
+Function
+.Fn elftc_string_table_destroy
+destroys the previously allocated string table specified by
+argument
+.Ar table ,
+and frees the internal resources allocated for it.
+.Pp
+Function
+.Fn elftc_string_table_from_section
+creates a new string table and initializes it based on the
+contents of the section specified by argument
+.Ar scn .
+This section must be of type
+.Dv SHT_STRTAB .
+The argument
+.Ar sizehint
+provides a hint about expected number of bytes of string data in the
+table.
+If the value of
+.Ar sizehint
+is zero, an implementation-default will be used instead.
+.Pp
+Function
+.Fn elftc_string_table_image
+returns a pointer to the ELF representation of the contents of the
+string table specified by argument
+.Ar table .
+If argument
+.Ar size
+is not NULL, the size of the ELF representation of the string table is
+stored in the location pointed to by argument
+.Ar size .
+The function
+.Fn elftc_string_table_image
+will compact the string table if the table contains deleted strings.
+The string offsets returned by prior calls to
+.Fn elftc_string_table_insert
+and
+.Fn elftc_string_table_lookup
+should be treated as invalid after a call to this function.
+.Pp
+Function
+.Fn elftc_string_table_insert
+inserts the NUL-terminated string pointed to by argument
+.Ar string
+into the string table specified by argument
+.Ar table ,
+and returns an offset value usable in ELF data structures.
+Multiple insertions of the same content will return the same offset.
+The offset returned will remain valid until the next call to
+.Fn elftc_string_table_image .
+.Pp
+Function
+.Fn elftc_string_table_lookup
+looks up the string referenced by argument
+.Ar string
+in the string table specified by argument
+.Ar table ,
+and if found, returns the offset associated with the string.
+The returned offset will be valid till the next call to function
+.Fn elftc_string_table_image .
+.Pp
+Function
+.Fn elftc_string_table_remove
+removes the string pointed by argument
+.Ar string
+from the string table referenced by argument
+.Ar table ,
+if it is present in the string table.
+.Pp
+Function
+.Fn elftc_string_table_to_string
+returns a pointer to the NUL-terminated string residing at argument
+.Ar offset
+in the string table specified by argument
+.Ar table .
+The value of argument
+.Ar offset
+should be one returned by a prior call to
+.Fn elftc_string_table_insert
+or
+.Fn elftc_string_table_lookup .
+The returned pointer will remain valid until the next call to
+.Fn elftc_string_table_insert
+or
+.Fn elftc_string_table_image .
+.Ss Memory Management
+The
+.Lb libelftc
+library manages its own memory allocations.
+The application should not free the pointers returned by the string
+table functions.
+.El
+.Sh IMPLEMENTATION NOTES
+The current implementation is optimized for the case where strings are
+added to a string table, but rarely removed from it.
+.Pp
+The functions
+.Fn elftc_string_table_insert ,
+.Fn elftc_string_table_lookup ,
+.Fn elftc_string_table_remove
+and
+.Fn elftc_string_table_to_string
+have O(1) asymptotic behavior.
+The function
+.Fn elftc_string_table_image
+can have O(size) asymptotic behavior, where
+.Ar size
+denotes the size of the string table.
+.Sh RETURN VALUES
+Functions
+.Fn elftc_string_table_create
+and
+.Fn elftc_string_table_from_section
+return a valid pointer to an opaque structure of type
+.Vt Elftc_String_Table
+on success, or NULL in case of an error.
+.Pp
+The function
+.Fn elftc_string_table_image
+returns a pointer to an in-memory representation of an ELF string
+table on success, or NULL in case of an error.
+.Pp
+Functions
+.Fn elftc_string_table_insert
+and
+.Fn elftc_string_table_lookup
+return a non-zero offset on success, or zero in case of an error.
+.Pp
+Function
+.Fn elftc_string_table_remove
+returns a positive value on success, or zero in case of an error.
+.Pp
+Function
+.Fn elftc_string_table_to_string
+returns a valid pointer on success, or NULL in case of an error.

+.Ft const char *
+.Fn elftc_version void
+.Sh DESCRIPTION
+Function
+.Fn elftc_version
+returns a project-wide identifier string that encodes the source
+revision of the project source tree.
+.Pp
+The returned identifier has four space-separated fields:
+.Bl -tag -width ".Em Project Branch"
+.It Em "Project-Name"
+This is always
+.Dq elftoolchain .
+.It Em "Project-Branch"
+The branch name for the project source tree.
+.It Em "Build-OS"
+The operating system that the tool chain was compiled for.
+.It Em "Version-Number"
+A tree-wide version number extracted from the version control
+system in use.
+.El
+.Sh RETURN VALUE
+Function
+.Fn elftc_program_version
+returns a pointer to an internal character buffer.
+.Sh EXAMPLES
+To retrieve and print the current toolchain version identifier, use:
+.Bd -literal -offset indent
+#include <sys/types.h>
+#include <libelftc.h>
+
+(void) printf("%s\en", elftc_version());
+.Ed
+.Pp
+On the HEAD branch of the project's sources, when checked out using
+Subversion and compiled on a NetBSD host, this would print:
+.D1 Dq elftoolchain HEAD NetBSD svn: Ns Em REVINFO
+where
+.Em REVINFO
+would be the current revision information for the project source tree.
+.Sh ERRORS
+Function
+.Fn elftc_program_version
