Is there any other API that I can use to accomplish launching a process and then reading from its stdout and writing to its stdin that works on both Jaguar and Panther using non NSTask stuff. I tried looking at popen's source and doing the pipes and forks like it does it but fdopen keeps returning EINVAL (22) not liking the "r+" mode I send it. Here is my ldpopen method: i call it using ldpopen(command, "r+"); static int pid = -1; static FILE * ldpopen(const char *command, const char *type) { char *argv[4]; int pdes[2]; FILE *iop; if (pipe(pdes) < 0) return (NULL); argv[0] = "sh"; argv[1] = "-c"; argv[2] = (char *)command; argv[3] = NULL; switch (pid = vfork()) { case -1: close(pdes[0]); close(pdes[1]); return NULL; case 0: close(pdes[0]); if (pdes[1] != STDOUT_FILENO) { (void)dup2(pdes[1], STDOUT_FILENO); (void)close(pdes[1]); errno = 0; int prob = dup2(STDOUT_FILENO, STDIN_FILENO); int y = errno; y = prob; } else if (pdes[1] != STDIN_FILENO) { (void)dup2(pdes[1], STDIN_FILENO); } execv(_PATH_BSHELL, argv); exit(127); } if (*type == 'r') { iop = fdopen(pdes[0], type); // this returns null with errno being 22 (void)close(pdes[1]); } else { iop = fdopen(pdes[1], type); (void)close(pdes[0]); } return iop; } Any help would be greatly appreciated, thanks.
