C programming getcwd variable manipulation

Question

Basically I need an if statement of which the response is dependent upon the current working directory.

I have done some research on the topic and I believe that the getcwd() function is what I am looking for, but I can't figure out how to interface with it in an if statement.

I am new to C, and the program I am making needs to be located on the Desktop (btw its a UNIX system) for it to run properly and the if statement needs to determine whether it is located on said desktop or not.

What about the following code it's work for me on ubuntu -

#include <stdlib.h>
#include <unistd.h>
#include <limits.h>

int main( void ){

    char* cwd;
    char buff[PATH_MAX + 1];

    cwd = getcwd( buff, PATH_MAX + 1 );
    if( cwd != NULL ) {
        printf( "My working directory is %s.\n", cwd );

        if(strcmp("/home/razib/Desktop", cwd) == 0) {
            printf("I'm in Desktop now\n");
        }
    }

    return EXIT_SUCCESS;
}   

Here you have to provide getcwd() method a buff[]. The buff[] may be declared with size PATH_MAX+1. PATH_MAX can be found at limits.h.

Hope it will help you.
Thanks a lot.
