進出口編程客戶機/服務器應用程序,客戶端提供文件名,則服務器將其發送給客戶端,客戶機將其保存..實現在Ubuntu的sigaction()信號()
,所以我想使信號處理程序來處理父母與子女之間的殭屍的問題,所以這個代碼信號:
enter code here
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 ???
缺少一些'#include'?在這裏(Fedora),你必須包含'',它是'sighandler_t',沒有'Sigfunc'的視線。 –
