pthread_mutex_consistent — make a robust mutex consistent
Compile and link with
This function makes a robust mutex consistent if it is in
an inconsistent state. A mutex can be left in an inconsistent
state if its owner terminates while holding the mutex, in
which case the next owner who acquires the mutex will succeed
and be notified by a return value of EOWNERDEAD from a call to
pthread_mutex_consistent() returns 0.
Otherwise, it returns a positive error number to indicate the
cause of the error.
simply informs the implementation that the state (shared
data) guarded by the mutex has been restored to a consistent
state and that normal operations can now be performed with
the mutex. It is the application_zsingle_quotesz_s responsibility to ensure
that the shared data has been restored to a consistent state
Before the addition of
pthread_mutex_consistent() to POSIX, glibc
defined the following equivalent nonstandard function if
_GNU_SOURCE was defined:
const pthread_mutex_t *mutex);
This GNU-specific API, which first appeared in glibc 2.4, is nowadays obsolete and should not be used in new programs.
