strcoll(3C)

strcoll -- string collation

Synopsis

   #include <string.h>
   
   int strcoll (const char s1, const char s2);

Description

strcoll returns an integer greater than, equal to, or less than zero in direct correlation 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)].

Both strcoll and strxfrm 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 is a more appropriate utility because the transformation process occurs only once.
