* Name: pthread_sigmask
|
|
*
|
|
* Description:
|
|
* This function is a simple wrapper around nxsig_procmask().
|
|
* See the nxsig_procmask() function description for further
|
|
* information.
|
|
*
|
|
* Input Parameters:
|
|
* how - How the signal mask will be changed:
|
|
* SIG_BLOCK - The resulting set is the union of
|
|
* the current set and the signal set
|
|
* pointed to by 'set'.
|
|
* SIG_UNBLOCK - The resulting set is the intersection
|
|
* of the current set and the complement
|
|
* of the signal set pointed to by 'set'.
|
|
* SIG_SETMASK - The resulting set is the signal set
|
|
* pointed to by 'set'.
|
|
* set - Location of the new signal mask
|
|
* oset - Location to store the old signal mask
|
|
*
|
|
* Returned Value:
|
|
* On success, this function will return 0 (OK). It will return EINVAL if
|
|
* how is invalid.
