    NAME

    pthread_rwlockattr_init, pthread_rwlockattr_destroy - initialize or destroy read-write lock attributes object
     
    

    SYNOPSIS

    cc -mt [ flag... ] file... -lpthread [ library... ]
    #include <pthread.h>
    
    int pthread_rwlockattr_init(pthread_rwlockattr_t *attr);
    

    int pthread_rwlockattr_destroy(pthread_rwlockattr_t *attr);
    

     

    DESCRIPTION

    The pthread_rwlockattr_init() function initializes a read-write lock attributes object attr with the default value for all of the attributes defined by the implementation.

    Results are undefined if pthread_rwlockattr_init() is called specifying an already initialized read-write lock attributes object.

    After a read-write lock attributes object has been used to initialize one or more read-write locks, any function affecting the attributes object (including destruction) does not affect any previously initialized read-write locks.

    The pthread_rwlockattr_destroy() function destroys a read-write lock attributes object. The effect of subsequent use of the object is undefined until the object is re-initialized by another call to pthread_rwlockattr_init(). An implementation can cause pthread_rwlockattr_destroy() to set the object referenced by attr to an invalid value.  

    RETURN VALUES

    If successful, the pthread_rwlockattr_init() and pthread_rwlockattr_destroy() functions return 0. Otherwise, an error number is returned to indicate the error.  

    ERRORS

    The pthread_rwlockattr_init() function will fail if:

    ENOMEM

    Insufficient memory exists to initialize the read-write lock attributes object.

    The pthread_rwlockattr_destroy() function may fail if:

    EINVAL

    The value specified by attr is invalid.
