semop - atomically perform operations on a set of semaphores
Semop is a Linux system call used to perform operations on a set of semaphores. It ensures that all operations specified in the argument
sops will either be completed or none of them will be performed at all. This call can be used for synchronization between threads or processes. The only drawback is that if the maximum number of semaphores allowed is reached, the call will fail.
int- ID of the set of semaphores.
struct sembuf*- pointer to an array of semaphore operations.
size_t- number of semaphores in the array.
- KU - Originated from kernel-space or user space.
- OPT - Optional argument - might not always be available (passed with null value)
To gain insight to the arguments passed to semop, as well as to log any broken semaphore constraints.
Example Use Case¶
If you need to synchronize between threads or processes, semop can be used to guarantee that a set of operations on a set of semaphores will either all succeed or none of them will.
If the maximum number of semaphores allowed is reached, the call will fail.
- semget - Gets an existing semaphore set or allocate a new one.
- semctl - Examine or change an existing semaphore set.
- semtimedop - Like
semop, but with an additional timeout parameter.
