SIGINFO (non-POSIX)

Default action: ignore
SA_SIGINFO macros

On some Unix-like platforms, SIGINFO is the signal sent to computer programs when a status request is received from the keyboard. The symbolic constant for SIGINFO is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms.

[edit] Etymology

SIG is a common prefix for signal names. INFO is an abbreviation for information request.
