ECHILDECHILD — No Child Processes
The calling process has no existing child processes to wait for.
SIGPIPE (13)The process attempted to write to a pipe or socket whose reading end has been closed.
The receiving process closed the connection before the sender finished writing. Common when piping output to commands that exit early.
Ignore SIGPIPE with signal(SIGPIPE, SIG_IGN) and check write() return values for EPIPE instead. Always ignore SIGPIPE in network servers.
ECHILDThe calling process has no existing child processes to wait for.
EINTRA blocking system call was interrupted by a signal before it could complete.
Exit 0The process completed successfully with no errors.
ENOEXECAn attempt was made to execute a file that is not in a recognized executable format.
SIGTTOU (22)A background process attempted to write to its controlling terminal when TOSTOP is set.
EMSGSIZEThe message is too large to be sent atomically through the socket or transport protocol.
