STRXFRM(3)                          Linux Programmer's Manual                          STRXFRM(3)



NAME
       strxfrm - string transformation

SYNOPSIS
       #include <string.h>

       size_t strxfrm(char *dest, const char *src, size_t n);

DESCRIPTION
       The  strxfrm() function transforms the src string into a form such that the result of str‐
       cmp(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 n bytes of the
       transformed string are placed in dest.  The transformation is based on the program's  cur‐
       rent 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 ('\0').  If the value returned is n  or
       more, the contents of dest are indeterminate.

CONFORMING TO
       SVr4, 4.3BSD, C89, C99.

NOTES
       In the POSIX or C locales strxfrm() is equivalent to copying the string with strncpy(3).
