Trylockshareduntil is a function commonly found in concurrent programming libraries, particularly in those that support reader-writer locks. This function attempts to acquire a shared (read) lock on a resource, but only if it can be done without waiting for an exclusive (write) lock to be released. If the lock cannot be acquired immediately, the function returns a failure indication instead of blocking the calling thread.
The primary purpose of trylockshareduntil is to provide a non-blocking mechanism for acquiring a shared lock,
The function typically takes two parameters: the first is a pointer to the reader-writer lock object, and
Trylockshareduntil is particularly useful in high-contention scenarios, where multiple threads frequently compete for access to a
