a simple snprintf truncating test

[James A Morrison]

Hi,

        Here is a really simple program that shows whether snprintf
truncates properly.  So far Solaris 5.6 acts the way I except it too.

#include <stdio.h>

/* A simple program to see if snprintf truncates properly */ 

int main(int argc, char* argv[]) {

        char* test;
        int retval=0;

        snprintf(test,5,"1234");

        if (!strcmp(test,"1234\0")) { 
                printf("Same length: Passed\n");
        } else {
                printf("Same length: Failed\n");
                retval++;
        }
        snprintf(test,5,"123");
        if(!strcmp(test,"123\0")) { 
                printf("Shorter: Passed\n");
        } else { 
                printf("Shorter: Failed\n");
                retval++;
        }
        snprintf(test,5,"123456");
        if(!strcmp(test,"1234\0")) { 
                printf("Longer: Passed\n");
        } else { 
                printf("Longer: Failed\n");
                retval++;
        }
        return retval;
}
