|
|
* Description:
|
|
* This function deletes the signal specified by signo from the signal
|
|
* set specified by the 'set' argument.
|
|
*
|
|
* Input Parameters:
|
|
* set - Signal set to delete the signal from
|
|
* signo - Signal to delete
|
|
*
|
|
* Returned Value:
|
|
* This is an internal OS interface and should not be used by applications.
|
|
* It follows the NuttX internal error return policy: Zero (OK) is
|
|
* returned on success. A negated errno value is returned on failure.
|
|
*
|
|
* EINVAL - The signo argument is invalid.
