I can't execute the program exactly!

#include <spawn.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <process.h>
#include <sys/wait.h>

main(int argc, char **argv)
{
char *args[] = { “c:/lt_work/child”, NULL };
int i, status;
pid_t pid;
struct inheritance inherit;

// create 3 child processes
for (i = 0; i < 3; i++) {
    inherit.flags = 0;
    if ((pid = spawn("c:/lt_work/child", 0, NULL, &inherit, args, environ)) == -1)
        perror("spawn() failed");
    else
        printf("spawned child, pid = %d\n", pid);
}

while (1) {
    if ((pid = wait(&status)) == -1) {
        perror("wait() failed (no more child processes?)");
        exit(EXIT_FAILURE);
    }
    printf("a child terminated, pid = %d\n", pid);
    
    if (WIFEXITED(status)) {
        printf("child terminated normally, exit status = %d\n",
            WEXITSTATUS(status));
    } else if (WIFSIGNALED(status)) {
        printf("child terminated abnormally by signal = %X\n",
            WTERMSIG(status));
    } // else see documentation for wait() for more macros
}

}

result of executing:
spawn() failed: no such file or directory
spawn() failed: no such file or directory
spawn() failed: no such file or directory
wait() failed (no more child processes?

I don’t know where is the problem?

you’ve got a hardcoded filepath beginning with ‘c:’, you’ll want to use a filepath that exists. Use the filepath to the executable as it appears under QNX and not Windows.

Thanks to theqman and I have resolved the problem:)
