man pthread

[Malcolm Douglas]

Sorry, not sure if this is the right way to handle this, but I saw a
doc error.

The pthread_cond_wait and pthread_cond_timedwait descriptions are
incorrect in man pthread.

The description is:
Wait for a condition and lock the specified mutex.

It should be:
Wait for a condition and unlock the specified mutex.

pthread_cond_timedwait has an analogous error.

The pages for man pthread_cond_wait and pthread_cond_timedwait do not
have this error, it is just in the descriptions in the page for
pthread.
