semop performs a set of operations on a message queue, just as semop. sops points to an array of type TSEMbuf. The array should contain nsops elements. The timeOut argument points to a time specification: if the operations cannot be performed withing the specified, time, the function will return with an error.
For more information on the actual operations, see semop.
