raise
Causes a signal to be raised.
Syntax
#include <signal.h>
int raise (int sig);
Parameters
sig A signal number specifying the signal to be raised.
Return Values
0 The signal was successfully raised.
!=0 The signal was not raised.
Description
The raise function causes the signal specified in sig to be raised to the
calling process.
The name and meaning of each signal is given below:
Name Description
SIGABRT Abnormal termination, (for example, by the abort function).
SIGFPE An erroneous arithmetic operation, (for example, divide by
0).
SIGILL An illegal instruction was executed (possibly after a
jump).
SIGINT An interactive interrupt signal was received.
SIGSEGV An invalid access to storage.
SIGTERM A termination request was sent to the program.
NOTE Signals are provided for conformance with ANSI C. However, the only
way to generate a signal on MPE/iX is by an explicit call to the
raise function. For information on a more comprehensive facility
for handling exceptions, see the Trap Handling Programmer's Guide.
