Standard C Library Functions strcoll(3C)
NAME
strcoll - string collation
SYNOPSIS
#include
int strcoll(const char *s1, const char *s2);
DESCRIPTION
Both strcoll() and strxfrm(3C) provide for locale-specific
string sorting. strcoll() is intended for applications in
which the number of comparisons per string is small. When strings are to be compared a number of times, strxfrm(3C) isa more appropriate function because the transformation pro-
cess occurs only once.The strcoll() function does not change the setting of errno
if successful. Since no return value is reserved to indicate an error, an application wishing to check for error situations should seterrno to 0, then call strcoll(), then check errno.
RETURN VALUES
Upon successful completion, strcoll() returns an integer
greater than, equal to, or less than zero in direct correla-
tion to whether string s1 is greater than, equal to, or less than the string s2. The comparison is based on strings interpreted as appropriate to the program's locale forcategory LC_COLLATE (see setlocale(3C)).
On error, strcoll() may set errno, but no return value is
reserved to indicate an error.ERRORS
The strcoll() function may fail if:
EINVAL The s1 or s2 arguments contain characters outside the domain of the collating sequence. FILES /usr/lib/locale/locale/locale.so.*LC_COLLATE database for locale

applications, as long as setlocale(3C) is not being called to change the locale.SEE ALSO
