- * Semaphore Manager
- *
- * DESCRIPTION:
- *
- * This package is the implementation of the Semaphore Manager.
- * This manager utilizes standard Dijkstra counting semaphores to provide
- * synchronization and mutual exclusion capabilities.
- *
- * Directives provided are:
- *
- * + create a semaphore
- * + get an ID of a semaphore
- * + delete a semaphore
- * + acquire a semaphore
- * + release a semaphore
- *

- * rtems_semaphore_obtain
- *
- * This directive allows a thread to acquire a semaphore.
- *
- * Input parameters:
- * id - semaphore id
- * option_set - wait option
- * timeout - number of ticks to wait (0 means wait forever)
- *
- * Output parameters:
- * RTEMS_SUCCESSFUL - if successful
- * error code - if unsuccessful
