Sends a signal to the executing program.
#include <signal.h>
int raise( int sig);
| sig | Signal to be raised |
The raise function sends sig to the executing program. If a signal-handling routine for sig has been installed by a prior call to signal, raise causes that routine to be executed. If no handler routine has been installed, the default action (as listed below) is taken.
The signal value sig can be one of the following manifest constants:
| Signal | Meaning | Default |
| SIGABRT | Abnormal termination. | Terminates the calling program with exit code 3. | |
| SIGFPE | Floating-point error. | Terminates the calling program. | |
| SIGILL | Illegal instruction. This signal is not generated by DOS, but is supported for ANSI compatibility. | Terminates the calling program. | |
| SIGINT | CTRL+ C interrupt. | Issues INT23H. | |
| SIGSEGV | Illegal storage access. This signal is not generated by DOS, but is supported for ANSI compatibility. | Terminates the calling program. | |
| SIGTERM | Termination request sent to the program. This signal is not generated by DOS, but is supported for ANSI compatibility., Ignores the signal. | ||
If successful, the raise function returns 0. Otherwise, it returns a nonzero value.
