These procedure names are the pTAL names for the corresponding C functions:
These functions comply with the POSIX.1 standard.
See the $SYSTEM.SYSTEM.HSIGNAL header file for the pTAL prototype definitions.
For a discussion of each parameter and procedure considerations, see the corresponding
sigaddset(3), sigdelset(3), sigemptyset(3), sigfillset(3), and
sigismember(3) function reference pages either online or in the Open System
Services Library Calls Reference Manual.
0D = Indicates a successful outcome.
-1D = Indicates an error. The reason for the error is given in the errno variable:
FE_EFAULT The address in signal-buffer is out of bounds.
FE_EINVAL SIG_IGN or SIG_ERR is passed to the handler.
FE_ERANGE length is less than the minimum required.
Use the ERRNO_GET_ procedure to obtain the value of errno in a
Guardian process.
