    about spawnl

    Such as:
    In DOS,I design a program--main.exe; in a menu,I want to run test.exe and return main.exe.but,now,when the test.exe finished,it cann't return main.exe.
    What can I do?

    ps:my english is poor.

    You have a parameter missing. Try


    Is test.exe definately being run?

    Try this code, and see if it works:
    #include <stddef.h>
    #include <process.h>
    #include <stdio.h>
    int main(void)
    	printf ("Before\n");
    	spawnl(P_WAIT,"temp.exe", "temp.exe", NULL);
    	printf ("After\n");
    	return (0);
    [edit]Note I called the child process temp.exe in this example[/edit]

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
