Macro Definition Documentation

PARTITION_INFORMATION_DEFINE

#define PARTITION_INFORMATION_DEFINE

(

max

)

Value:

OBJECTS_INFORMATION_DEFINE( \
    _Partition, \
    OBJECTS_CLASSIC_API, \
    OBJECTS_RTEMS_PARTITIONS, \
    Partition_Control, \
    max, \

Function Documentation

_Partition_Allocate()

static __inline__ Partition_Control* _Partition_Allocate ( void  )

static

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.

Definition at line 129 of file partimpl.h.

_Partition_Allocate_buffer()

static __inline__ void* _Partition_Allocate_buffer ( Partition_Control *  the_partition )

static

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.

Definition at line 44 of file partimpl.h.

_Partition_Free()

static __inline__ void _Partition_Free ( Partition_Control *  the_partition )

static

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.

Definition at line 172 of file partimpl.h.

_Partition_Free_buffer()

static __inline__ void _Partition_Free_buffer ( Partition_Control *  the_partition, Chain_Node *  the_buffer  )

static

Frees the_buffer to the_partition.

This routine frees the_buffer to the_partition.

Definition at line 56 of file partimpl.h.

_Partition_Is_buffer_on_boundary()

static __inline__ bool _Partition_Is_buffer_on_boundary ( void *  the_buffer, Partition_Control *  the_partition  )

static

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.

Definition at line 70 of file partimpl.h.

_Partition_Is_buffer_valid()

static __inline__ bool _Partition_Is_buffer_valid ( Chain_Node *  the_buffer, Partition_Control *  the_partition  )

static

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.
