NAME
strxfrm - string transformation
LIBRARY
Standard C library
( libc,~ -lc)
SYNOPSIS
#include <string.h>
size_t strxfrm(size_t size;
char dest[restrict size], const char src[restrict size],
size_t size);
DESCRIPTION
The
strxfrm()
function transforms the
src
string into a
form such that the result of
strcmp(3)
on two strings that have
been transformed with
strxfrm()
is the same as the result of
strcoll(3)
on the two strings before their transformation.
The first
size
bytes of the transformed string are placed in
dest.
The transformation is based on the program's current
locale for category
LC_COLLATE.
(See
setlocale(3)).
RETURN VALUE
The
strxfrm()
function returns the number of bytes required to
store the transformed string in
dest
excluding the
terminating null byte ([aq][rs]0[aq]).
If the value returned is
size
or more, the
contents of
dest
are indeterminate.
