strcmpi()

Compare two strings, ignoring case

Synopsis:

#include <string.h>

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

Arguments:

s1, s2
The strings that you want to compare.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The strcmpi() function compares the string pointed to by s1 to the string pointed to by s2, ignoring case.

All uppercase characters from s1 and s2 are mapped to lowercase for the purposes of doing the comparison. The strcmpi() function is identical to the stricmp() function.

Returns:

< 0
s1 is less than s2.
0
s1 is equal to s2.
> 0
s1 is greater than s2.

Examples:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main( void )
{
    printf( "%d\n", strcmpi( "AbCDEF", "abcdef" ) );
    printf( "%d\n", strcmpi( "abcdef", "ABC"    ) );
    printf( "%d\n", strcmpi( "abc",    "ABCdef" ) );
    printf( "%d\n", strcmpi( "Abcdef", "mnopqr" ) );
    printf( "%d\n", strcmpi( "Mnopqr", "abcdef" ) );

    return EXIT_SUCCESS;
}

produces the output:

0
100
-100
-12
12
