Questions tagged [sigpipe]

SIGPIPE is the signal sent to a process when it attempts to write to a pipe without a process connected to the other end.

On POSIX-compliant platforms, SIGPIPE is the signal sent to a process when it attempts to write to a pipe without a process connected to the other end. The symbolic constant for SIGPIPE is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms.

Why does this C program generate SIGPIPE later than expected?

This program generates SIGPIPE after piping it to "head -n 1", after a random time. I understand that because we're feeding more to "head -n 1" after the first line, we would expect it to generate SIGPIPE, but instead it will make it to a random…
