SYNOPSIS

     #include <string.h>

     size_t
     strxfrm(char * restrict dst, const char * restrict src, size_t n);

     #include <xlocale.h>

     size_t
     strxfrm_l(char * restrict dst, const char * restrict src, size_t n,
         locale_t loc);

DESCRIPTION

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

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

     While the strxfrm() function uses the current locale, the strxfrm_l()
     function may be passed a locale directly. See xlocale(3) for more infor-
     mation.

RETURN VALUES

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