166 ; * Description: This function checks the semaphore to see if a resource is available or, i

task if the
168 ; * resource is not available or the event did not occur.
169 ; *
170 ; * Arguments : pevent is a pointer to the event control block
171 ; *
172 ; * Returns : > 0 if the resource is available or the event did not occur the sem
aphore is
173 ; * decremented to obtain the resource.
174 ; * == 0 if the resource is not available or the event did not occur or,
175 ; * if 'pevent' is a NULL pointer or,
176 ; * if you didn't pass a pointer to a semaphore
