Compare two strings up to a given length, ignoring case
#include <string.h>
int strnicmp( const char* s1,
const char* s2,
size_t len );
- s1, s2
- The strings that you want to compare.
- len
- The maximum number of characters that you want to compare.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The strnicmp() function compares
up to len characters from the strings pointed to by
s1 and s2, ignoring case.
- < 0
- s1 is less than s2.
- 0
- s1 is equal to s2.
- > 0
- s1 is greater than s2.
