Initializes a signal set to the full set.
Syntax |
 |
#include <signal.h>
int sigfillset (sigset_t *set);
|
Parameters |
|
- set
A pointer to a structure of type sigset_t to initialize to the full set.
Return Values |
|
- 0
Success.
- -1
An error occurred. The signal set is not initialized, and errno is set to indicate the error condition.
Description |
|
The sigfillset() function initializes set to the full set. All signals described in Table 3-6 “POSIX/iX Signals” are included in the set.
The sigfillset() or sigemptyset() function must be called to initialize 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.
Errors |
|
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. |
| | ACTION | Make sure that the pointer is correctly initialized. |
