Question
This code is supposed to be able to test a driver or make a driver work...but so far I keep getting errors. How do you correct this code?

strcpy(argv[2], FILE_SOURCE);
argv[3] = (char *) malloc(strlen(FILE_SINK)+1);
strcpy(argv[3], FILE_SINK);
}
// Initialize the a: floppy disk

Explanation / Answer
just included the stdlib.h ,no warnings,if you have fsAPI.h ,copy that file in include folder after that you will get no errors,
the code after modification is
#include <assert.h>
#include <stdio.h>
#include <string.h>
#include<stdlib.h>
#include <fsAPI.h>
#define DEBUG
#define MAX_FILE_NAME 24
#define FILE_SOURCE "client.c"
#define FILE_SINK "newby.c"
#define DIR "CXXFILES.DIR"
void makeDOSFileName(char *, char *);
int main( int argc, char *argv[]) {
char fileName1[MAX_FILE_NAME], fileName2[MAX_FILE_NAME];
const int result = 1;
// Get parameters from command line
if(argc != 4) {
// fprintf(stderr, "Usage: fs <dir> <file_source> <file_sink> ");
// exit(1);
argv[1] = (char *)malloc(strlen(DIR)+1);
strcpy(argv[1], DIR);
argv[2] = (char *) malloc(strlen(FILE_SOURCE)+1);
strcpy(argv[2], FILE_SOURCE);
argv[3] = (char *) malloc(strlen(FILE_SINK)+1);
strcpy(argv[3], FILE_SINK);
}
// Initialize the a: floppy disk
fd_load('a'); // (There is no b: on my machine)
// Test directory listing function
printf("List the root directory ");
fd_ls();
// Test the change directory function -- first down
makeDOSFileName(argv[1], fileName1);
printf("Change the current directory to %s ", fileName1);
if(!fd_cd(fileName1)) {
fprintf(stderr, "Main: fd_cd("%s") failed ", fileName1);
}
printf("List the new current directory ");
fd_ls();
printf(" ");
