STRXFRM(3)		 BSD Library Functions Manual		    STRXFRM(3)

NAME
     strxfrm --	transform a string under locale

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <string.h>

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

     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().

     strxfrm_l() does the same,	however	takes an explicit locale rather	than
     the global	locale.

RETURN VALUES
     Upon successful completion, strxfrm() and strxfrm_l() return the length
     of	the transformed	string not including the terminating null character.
     If	this value is n	or more, the contents of dst are indeterminate.

SEE ALSO
     setlocale(3), strcmp(3), strcoll(3), wcsxfrm(3)

STANDARDS
     The strxfrm() function conforms to	ISO/IEC	9899:1990 ("ISO	C90").	The
     strxfrm_l() function conforms to IEEE Std 1003.1-2008 ("POSIX.1").
