    NAME

    
    
    rfork_thread
    
     - create a rfork-based process thread
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <unistd.h>
    pid_t rfork_thread (int flags void *stack int (*func)(void *arg) void *arg);
     

    DESCRIPTION

    The rfork_thread ();
    function is a helper function for rfork(2). It arranges for a new process to be created and the child process will call the specified function with the specified argument, while running on the supplied stack.

    Using this function should avoid the need to implement complex stack swap code.  

    RETURN VALUES

    Upon successful completion, rfork_thread ();
    returns the process ID of the child process to the parent process. Otherwise, a value of -1 is returned to the parent process, no child process is created, and the global variable errno is set to indicate the error.

    The child process context is not aware of a return from the rfork_thread ();
    function as it begins executing directly with the supplied function.  

    ERRORS

    See rfork(2) for error return codes.  

    SEE ALSO

    fork(2), intro(2), minherit(2), rfork(2), vfork(2)  

    HISTORY

    The rfork_thread ();
    function first appeared in Fx 4.3 .
