Function Documentation

_POSIX_RWLock_Allocate()

RTEMS_INLINE_ROUTINE POSIX_RWLock_Control* _POSIX_RWLock_Allocate

(

void

)

Allocate a RWLock control block.

This function allocates a RWLock control block from the inactive chain of free RWLock control blocks.

References _Objects_Allocate().

_POSIX_RWLock_Free()

RTEMS_INLINE_ROUTINE void _POSIX_RWLock_Free

(

POSIX_RWLock_Control *

the_RWLock

)

Free a RWLock control block.

This routine frees a RWLock control block to the inactive chain of free RWLock control blocks.

_POSIX_RWLock_Manager_initialization()

void _POSIX_RWLock_Manager_initialization

(

void

)

POSIX RWLock manager initialization.

This routine performs the initialization necessary for this manager.

POSIX RWLock manager initialization.

References _Objects_Initialize_information(), and _POSIX_RWLock_Information.

_POSIX_RWLock_Translate_core_RWLock_return_code()

int _POSIX_RWLock_Translate_core_RWLock_return_code

(

CORE_RWLock_Status

the_RWLock_status

)

POSIX translate core RWLock return code.

This routine translates SuperCore RWLock status codes into the corresponding POSIX ones.

Parameters

[in]

the_RWLock_status

is the SuperCore status.

Returns

the corresponding POSIX status

Return values

0	The status indicates that the operation completed successfully.
EINVAL	The status indicates that the thread was blocked waiting for an operation to complete and the RWLock was deleted.
EBUSY	This status indicates that the RWLock was not immediately available.
ETIMEDOUT	This status indicates that the calling task was willing to block but the operation was unable to complete within the time allotted because the resource never became available.
