strcoll
, strcoll_l
— compare strings, according to current
collation
Standard C Library (libc, -lc)
#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);
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 current
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.
The strcoll
() function conforms to
ISO/IEC 9899:1990
(“ISO C90”).
