Detailed Description

Macro Definition Documentation

PARTITION_INFORMATION_DEFINE

#define PARTITION_INFORMATION_DEFINE

(

max

)

Value:

OBJECTS_INFORMATION_DEFINE( \
    _Partition, \
    OBJECTS_CLASSIC_API, \

Function Documentation

_Partition_Allocate()

RTEMS_INLINE_ROUTINE Partition_Control* _Partition_Allocate

(

void

)

Allocates a partition control block from the inactive chain of free partition control blocks.

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

_Partition_Allocate_buffer()

RTEMS_INLINE_ROUTINE void* _Partition_Allocate_buffer

(

Partition_Control *

the_partition

)

Allocate a buffer from the_partition.

This function attempts to allocate a buffer from the_partition. If successful, it returns the address of the allocated buffer. Otherwise, it returns NULL.

_Partition_Free()

RTEMS_INLINE_ROUTINE void _Partition_Free

(

Partition_Control *

the_partition

)

Frees a partition control block to the inactive chain of free partition control blocks.

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

_Partition_Free_buffer()

RTEMS_INLINE_ROUTINE void _Partition_Free_buffer	(	Partition_Control *	the_partition,
		Chain_Node *	the_buffer
	)

Frees the_buffer to the_partition.

This routine frees the_buffer to the_partition.

_Partition_Is_buffer_on_boundary()

RTEMS_INLINE_ROUTINE bool _Partition_Is_buffer_on_boundary	(	void *	the_buffer,
		Partition_Control *	the_partition
	)

Checks whether is on a valid buffer boundary for the_partition.

This function returns TRUE if the_buffer is on a valid buffer boundary for the_partition, and FALSE otherwise.

_Partition_Is_buffer_valid()

RTEMS_INLINE_ROUTINE bool _Partition_Is_buffer_valid	(	Chain_Node *	the_buffer,
		Partition_Control *	the_partition
	)

Checks whether the_buffer is a valid buffer from the_partition.

This function returns TRUE if the_buffer is a valid buffer from the_partition, otherwise FALSE is returned.
