SIGQUIT is a signal used on POSIX-compliant platforms to indicate a request by a user for a process to dump core. The symbolic constant for SIGQUIT is defined in the header file signal.h; on the vast majority of systems it is signal #3.
SIGQUIT can usually be induced with Ctrl-\. On Linux, one may also use Ctrl-4 or, on the virtual console, the SysRq key.
