Create a read-write lock attribute object
#include <pthread.h> int pthread_rwlockattr_init( pthread_rwlockattr_t* attr );
- A pointer to the pthread_rwlockattr_t object that you want to initialize.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_rwlockattr_init() function initializes the specified read-write lock attribute object to its default values.
Changes made to a read-write lock attribute object changes after it's been used to initialize a read-write lock won't affect the previously initialized read-write locks.
- There isn't enough memory available to initialize attr.
