NAME

     strxfrm, strxfrm_l -- transform a string under locale

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     size_t
     strxfrm(char *restrict s1, const char *restrict s2, size_t n);

     #include <string.h>
     #include <xlocale.h>

     size_t
     strxfrm_l(char *restrict s1, const char *restrict s2, size_t n, locale_t loc);

DESCRIPTION

     The strxfrm() function transforms a null-terminated string pointed to by s2 according to the current locale collation if any, then copies the
     transformed string into s1.  Not more than n characters are copied into s1, including the terminating null character added.  If n is set to 0
     (it helps to determine an actual size needed for transformation), s1 is permitted to be a NULL pointer.

     Comparing two strings using strcmp() after strxfrm() is equal to comparing two original strings with strcoll().

     Although the strxfrm() function uses the current locale, the strxfrm_l() function may be passed a locale directly. See xlocale(3) for more
     information.

RETURN VALUES

     Upon successful completion, strxfrm() returns the length of the transformed string not including the terminating null character.  If this
     value is n or more, the contents of s1 are indeterminate.

STANDARDS

     The strxfrm() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
