Function Documentation

status_t rdwrl_timedreq(struct rdwrlock *const rdwr, enum rdwrlock_scope scope, const struct timespec *const to)

Request to enter a critical section with a timeout.

This function is part of a fair (i.e. no rd/wr preference) sequence that guarantees that no reader or write will starve.

Parameters:

• rdwr – The lock handle.

• scope – The scope of the privileges requested.

• to – A RELATIVE timeout, NOT an ABSOLUTE timeout, as the POSIX standard specifies. This function converts the relative timeout to absolute timeout required.

Returns:

status_t.
