type: OTHER
value: the calling process blocks
type: OTHER
Source sentences:
text: If the new value of the semaphore variable is negative, the process executing wait is blocked (i.e., added to the semaphore's queue).
text: However, If the value of wait is positive, then the value of the wait argument X is decremented.
text: Semaphore will always hold a non-negative integer value.
text: Binary Semaphores can assume only the value 0 or the value 1 counting semaphores also called general semaphores can assume only nonnegative values.
text: { select a process from L; //if the value of semaphore is positive //then
text: Counting semaphore can take nonnegative integer values.
text: If the new value of the semaphore variable is negative, the process executing is blocked (i.e., added to the semaphore's queue).
text: After the increment, if the pre-increment value was negative (meaning there are processes waiting for a resource), it transfers a blocked process from the semaphore's waiting queue to the ready queue.
text: No operation is executed if the value of the argument is negative or zero.
text: After the increment if the value is negative, it transfers a blocked process from the semaphore's queue to the ready queue.
text: After the increment, if the value was negative (meaning there are processes waiting for a resource), it transfers a blocked process from the semaphore's waiting queue to the ready queue.
text: After the increment, if the pre-increment value was negative (meaning there are processes waiting for a resource), it transfers a blocked process from the semaphore's waiting queue to the ready queue.
text: wait: if the value of semaphore variable is negative or zero, add the process executing wait to the semaphore's queue and set its state to blocked.
text: Since the old value was negative it will release one waiter, but subsequent calls to signal() will not release any.
text: This value may be negative, in which case releases must occur before any acquires will be granted.
text: This value may be negative, in which case releases must occur before any acquires will be granted.
text: If the value of counting semaphore is negative then it states the number of processes in the blocked state while if it is positive then it states the number of slots available in the critical section.
text: This value may be negative, in which case releases must occur before any acquires will be granted.
text: If the value of the semaphore is negative, the calling process blocks; one of the blocked processes wakes up when another process calls sem_post .
text: The wait() function is used to decrement the value of the semaphore variable "S" by one if the value of the semaphore variable is positive.
text: If the value of Wait is positive, then the value of the wait argument S is decremented.
text: If the value of the semaphore is positive, the process can use the resource.
text: In the P operation, the semaphore's value must be positive just before it is decremented (resulting in a value that is guaranteed to be nonnegative and one less than what it was before it was decremented).
text: Only after both threads have completed will the semaphore's value be positive and A be able to continue.
text: A thread that invokes down() waits until the value is positive before decrementing the value.
text: () waits until the value of s is positive, then decrements the value of s. java.lang.String toString()
text: () waits until the value of s is positive, then decrements the value of s.
text: If the value is positive,that value equals the number of processes that can issue a wait and immediately continue to execute.
text: Semaphores are a shareable resource that take on a non-negative integer value.
