## Enumerations
enum | Processor_mask_Copy_status { PROCESSOR_MASK_COPY_LOSSLESS , PROCESSOR_MASK_COPY_PARTIAL_LOSS , PROCESSOR_MASK_COPY_COMPLETE_LOSS , PROCESSOR_MASK_COPY_INVALID_SIZE }

## Functions
typedef | BITSET_DEFINE (Processor_mask, CPU_MAXIMUM_PROCESSORS) Processor_mask
| A bit map which is large enough to provide one bit for each processor in the system.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Zero (Processor_mask *mask)
| Sets the bits of the mask to zero, also considers CPU_MAXIMUM_PROCESSORS.
RTEMS_INLINE_ROUTINE bool | _Processor_mask_Is_zero (const Processor_mask *mask)
| Checks if the mask is zero, also considers CPU_MAXIMUM_PROCESSORS.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Fill (Processor_mask *mask)
| Fills the mask, also considers CPU_MAXIMUM_PROCESSORS.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Assign (Processor_mask *dst, const Processor_mask *src)
| Copies the mask to another mask, also considers CPU_MAXIMUM_PROCESSORS.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Set (Processor_mask *mask, uint32_t index)
| Sets the specified index bit of the mask.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Clear (Processor_mask *mask, uint32_t index)
| Clears the specified index bit of the mask.
RTEMS_INLINE_ROUTINE bool | _Processor_mask_Is_set (const Processor_mask *mask, uint32_t index)
| Checks if the specified index bit of the mask is set.
RTEMS_INLINE_ROUTINE bool | _Processor_mask_Is_equal (const Processor_mask *a, const Processor_mask *b)
| Checks if the processor sets a and b are equal.
RTEMS_INLINE_ROUTINE bool | _Processor_mask_Has_overlap (const Processor_mask *a, const Processor_mask *b)
| Checks if the intersection of the processor sets a and b is non-empty.
RTEMS_INLINE_ROUTINE bool | _Processor_mask_Is_subset (const Processor_mask *big, const Processor_mask *small)
| Checks if the processor set small is a subset of processor set big.
RTEMS_INLINE_ROUTINE void | _Processor_mask_And (Processor_mask *a, const Processor_mask *b, const Processor_mask *c)
| Performs a bitwise a = b & c.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Nand (Processor_mask *a, const Processor_mask *b, const Processor_mask *c)
| Performs a bitwise a = b & ~c.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Or (Processor_mask *a, const Processor_mask *b, const Processor_mask *c)
| Performs a bitwise a = b | c.
RTEMS_INLINE_ROUTINE void | _Processor_mask_Xor (Processor_mask *a, const Processor_mask *b, const Processor_mask *c)
| Performs a bitwise a = b ^ c.
RTEMS_INLINE_ROUTINE uint32_t | _Processor_mask_Count (const Processor_mask *a)
| Gets the number of set bits in the processor mask.
RTEMS_INLINE_ROUTINE uint32_t | _Processor_mask_Find_last_set (const Processor_mask *a)
| Finds the last set of the processor mask.
RTEMS_INLINE_ROUTINE uint32_t | _Processor_mask_To_uint32_t (const Processor_mask *mask, uint32_t index)
| Returns the subset of 32 processors containing the specified index as an unsigned 32-bit integer.
RTEMS_INLINE_ROUTINE void | _Processor_mask_From_uint32_t (Processor_mask *mask, uint32_t bits, uint32_t index)
| Creates a processor set from an unsigned 32-bit integer relative to the specified index.
RTEMS_INLINE_ROUTINE void | _Processor_mask_From_index (Processor_mask *mask, uint32_t index)
| Creates a processor set from the specified index.
RTEMS_INLINE_ROUTINE bool | _Processor_mask_Is_at_most_partial_loss (Processor_mask_Copy_status status)
| Checks if the copy status guarantees at most partial loss.
Processor_mask_Copy_status | _Processor_mask_Copy (long *dst, size_t dst_size, const long *src, size_t src_size)
| Copies one mask to another.
RTEMS_INLINE_ROUTINE Processor_mask_Copy_status | _Processor_mask_To_cpu_set_t (const Processor_mask *src, size_t dst_size, cpu_set_t *dst)
| Copies one mask to another.
