strnicmp, _fstrnicmp

Compares a portion of one string to a portion of another, without case sensitivity.

Defined in header <string.h>

Syntax

#include <string.h>
Near version: int strnicmp(const  char *sl, const char *s2, size_t maxlen);
Far version: int far _fstrnicmp(const char far *sl, const char far *s2,
                                size_t maxlen)

Portability

Remarks

of maxlen bytes, starting with the first character in each string and continuing with subsequent cliaracters 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 si (or part of it) to s2 (or part of it).

Retum value

strnicmp returns an int value that is

< 0 if s2 is less than s2 == 0 if si is the same as s2 > 0 if s2 is greater than s2

Example

#include <string.h>
#include <stdio.h>
int main(void)
{
   char *bufl = "BBBccc",  *buf2 = "bbbccc";
   int ptr;
   ptr = strnicmp (buf2, bufl, 3);
   if (ptr > 0)
      printf ("buffer 2 is greater than buffer l\n"
   if (ptr < 0)
      printf ("buffer 2 is less than buffer l\n");
   if (ptr == 0)
      printf ("buffer 2 equals buffer l\n");
   return 0;
