Detailed Description

Macro Definition Documentation

POSIX_KEYS_INFORMATION_DEFINE

#define POSIX_KEYS_INFORMATION_DEFINE

(

max

)

Value:

OBJECTS_INFORMATION_DEFINE( \
  _POSIX_Keys, \
  OBJECTS_POSIX_API, \
  OBJECTS_POSIX_KEYS, \
  POSIX_Keys_Control, \
  max, \
  OBJECTS_NO_STRING_NAME, \
  NULL \
)

Macro to define the objects information for the POSIX Key objects.

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

Parameters

max	The configured object maximum (the OBJECTS_UNLIMITED_OBJECTS flag may be set).

POSIX_KEYS_RBTREE_NODE_TO_KEY_VALUE_PAIR

#define POSIX_KEYS_RBTREE_NODE_TO_KEY_VALUE_PAIR

(

node

)

Value:

RTEMS_CONTAINER_OF( node, POSIX_Keys_Key_value_pair, Lookup_node )

Variable Documentation

_POSIX_Keys_Key_value_pair_maximum

const uint32_t _POSIX_Keys_Key_value_pair_maximum

extern

The POSIX key and value pairs maximum.

This value is provided via <rtems/confdefs.h> in case POSIX key and value pairs are configured. The OBJECTS_UNLIMITED_OBJECTS flag may be set.

_POSIX_Keys_Key_value_pairs

POSIX_Keys_Key_value_pair _POSIX_Keys_Key_value_pairs[]

extern

The initial set of POSIX key and value pairs.

This array is provided via <rtems/confdefs.h> in case POSIX key and value pairs are configured. The POSIX key and value pair count in this array must be equal to _Objects_Maximum_per_allocation( _POSIX_Keys_Key_value_pair_maximum ).
