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.
