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 :
The filename is : myHeader.hCode: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 */
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
