Hi...
Im programming client/server app that client provide the file name then the server send it to client then the client will save it ..

so i want to make signal handler to handle zombie problem between parent and child so this code for signal :

Code:
Sigfunc *
signal(int signo, Sigfunc *func)
{
    struct sigaction    act, oact;

    act.sa_handler = func;
    sigemptyset(&act.sa_mask);
    act.sa_flags = 0;
    if (signo == SIGALRM) {
#ifdef    SA_INTERRUPT
        act.sa_flags |= SA_INTERRUPT;    /* SunOS 4.x */
#endif
    } else {
#ifdef    SA_RESTART
        act.sa_flags |= SA_RESTART;        /* SVR4, 44BSD */
#endif
    }
    if (sigaction(signo, &act, &oact) < 0)
        return(SIG_ERR);
    return(oact.sa_handler);
}
/* end signal */
The filename is : myHeader.h
and the error when compile the file is :

gcc -Wall -I/home/zmhnk/Desktop/ -o "myHeader" "myHeader.h" (in directory: /home/zmhnk/Desktop)
myHeader.h:281:1: error: unknown type name ‘Sigfunc’
myHeader.h:282:19: error: unknown type name ‘Sigfunc’
Compilation failed.

so how to solve this problem
