Macro to define the objects information for the Classic Partition objects.

This macro should only be used by <rtems/confdefs.h>.

Parameters
maxThe configured object maximum (the OBJECTS_UNLIMITED_OBJECTS flag may be set).

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.

Definition at line 91 of file partimpl.h.
