strcasecmp() is a case insensitive string compare function. Not usually bundled with many default libraries.

Here is a version of the function for ya...

int cstrcmp(s1, s2)     /* also known as strcasecmp() */
register char *s1, *s2;
{
   while(tolower(*s1) == tolower(*s2++))
      if(*s1++ == '\0')
         return(0);
   return(tolower(*s1) - tolower(*--s2));
}
 
int cstrncmp(s1, s2, n) /* also known as strncasecmp() */
register char *s1, *s2;
register int n;
{
   while(--n >= 0 && tolower(*s1) == tolower(*s2++))
      if(*s1++ == '\0')
         return(0);
   return(n < 0 ? 0 : tolower(*s1) - tolower(*--s2));
}
 
Hope that helps!
