int sigfillset (sigset_t *set);

Description
The sigfillset() function initializes set to the full set. All signals
described in Table 3-5 are included in the set.

the structure of type sigset_t pointed to by set prior to its use by
other functions.
Implementation Considerations
Refer to the EFAULT error description below.

If an error occurs, errno is set to the following value:
EFAULT CAUSE The system detected a NULL or bad address in
attempting to use the set parameter.
