Standard C Library Functions                          strcoll(3C)

NAME

strcoll - string collation

SYNOPSIS

#include <string.h> 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) is a more appropriate function because the transformation pro- cess occurs only once.

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 for category 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.

NOTES

The strcoll() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale. SunOS 5.8 Last change: 20 Dec 1996 2
