Program received signal SIGPIPE, Broken pipe

The process received a SIGPIPE. The default behaviour for this signal is to end the process.

A SIGPIPE is sent to a process if it tried to write to a socket that had been shutdown for writing or isn’t connected (anymore).

To avoid that the program ends in this case, you could either

  • make the process ignore SIGPIPE#include <signal.h> int main(void) { sigaction(SIGPIPE, &(struct sigaction){SIG_IGN}, NULL); ... or
  • install an explicit handler for SIGPIPE (typically doing nothing):#include <signal.h> void sigpipe_handler(int unused) { } int main(void) { sigaction(SIGPIPE, &(struct sigaction){sigpipe_handler}, NULL); ...

In both cases send*()/write() would return -1 and set errno to EPIPE.
