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

int wcscoll(const wchar_t *s1, const wchar_t *s2); 

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

int _wcsicoll(const wchar_t *s1, wconst_t char *s2); 

int _mbscoll(const unsigned char *s1, const unsigned char *s2); 

int _mbsicoll(const unsigned char *s1, const unsigned char *s2); 

Description 

Compares two strings. 

strcoll compares the string pointed to by s1 to the string pointed to by s2, according to the current locale's LC_COLLATE category. 

_stricoll performs like strcoll but is not case sensitive.

The real collation (_lstricoll) returns -1, 0 or 1, whereas _stricoll does a codepoint comparison, and returns < 0, 0 or > 0. 

Return Value  

Example

#include <stdio.h>
#include <string.h>
int main(void)
{
   char *two = "International";
   char *one = "Borland";
   int check;
   check = strcoll(one, two);
   if (check == 0)
      printf("The strings are equal\n");
   if (check <  0)
      printf("%s comes before %s\n", one, two);
   if (check >  0)
      printf("%s comes before %s\n", two, one);
   return 0;
}
