_sleepon_destroy()
Destroy a sleepon
Synopsis:
#include <pthread.h>
int _sleepon_destroy( sleepon_t * l );
Arguments:
- l
- A pointer to a sleepon_t that you created by calling _sleepon_init().
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The _sleepon_destroy() function destroys a sleepon_t structure, l, that's been previously initialized by _sleepon_init().
If l hasn't been locked by _sleepon_lock(), _sleepon_destroy() locks it before destroying it.
The sleepon structure is reference-counted such that, if other threads are blocked waiting for a condition, they're be signaled to wake up, and the last one to wake up frees the memory allocated to the sleepon.
Returns:
- 0
- Success.
- ≠0
- Failure.
