Prototype 

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

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

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

Description 

Compares one string to another, without case sensitivity. 

stricmp performs an unsigned comparison of s1 to s2, starting with the first character in each string and continuing with subsequent characters until the corresponding characters differ or until the end of the strings is reached. The comparison is not case sensitive. 

It returns a value (< 0, 0, or > 0) based on the result of comparing s1 (or part of it) to s2 (or part of it). 

The routines stricmp and strcmpi are the same; strcmpi is implemented through a macro in string.h that translates calls from strcmpi to stricmp. Therefore, in order to use stricmp, you must include the header file string.h for the macro to be available. 

Return Value  

Example

#include <string.h>
#include <stdio.h>
int main(void)
{
   char *buf1 = "BBB", *buf2 = "bbb";
   int ptr;
   ptr = stricmp(buf2, buf1);
   if (ptr > 0)
      printf("buffer 2 is greater than buffer 1\n");
   if (ptr < 0)
      printf("buffer 2 is less than buffer 1\n");
   if (ptr == 0)
      printf("buffer 2 equals buffer 1\n");
   return 0;
}
