STRCOLL(3)						   BSD Library Functions Manual 						STRCOLL(3)

NAME

     strcoll -- compare strings according to current collation

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     int
     strcoll(const char *s1, const char *s2);

     int
     strcoll_l(const char *s1, const char *s2, locale_t loc);

DESCRIPTION

     The strcoll() function lexicographically compares the null-terminated strings s1 and s2 according to the current locale collation and returns
     an integer greater than, equal to, or less than 0, depending on whether s1 is greater than, equal to, or less than s2.  If information about
     the current locale collation is not available, the value of strcmp(s1, s2) is returned.  The strcoll_l() function uses an explicit locale
     argument rather than the system locale.

SEE ALSO

     setlocale(3), strcmp(3), strxfrm(3), wcscoll(3)

STANDARDS

     The strcoll() function conforms to ISO/IEC 9899:1990 (``ISO C90'').  The strcoll_l() function conforms to IEEE Std 1003.1-2008 (``POSIX.1'').

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 comparing 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 charac-
     ter.  If this value is n or more, the contents of dst are indeterminate.

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