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

NAME

     strcoll, strcoll_l -- compare strings, according to current collation

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

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

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

     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, according as s1 is greater than, equal to, or less than s2.  If information about the cur-
     rent locale collation is not available, the value of strcmp(s1, s2) is returned.

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

SEE ALSO

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

STANDARDS

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

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'').
