Macro Definition Documentation


#define QF_MPOOL_EL (   evType_)     struct { void *sto_[((sizeof(evType_) - 1U)/sizeof(void*)) + 1U]; }

Memory pool element to allocate correctly aligned storage for QMPool class.

[in]evType_event type (name of the subclass of QEvt)

Typedef Documentation

◆ QMPoolSize

typedef uint8_t QMPoolSize

The data type to store the block-size based on the macro #QF_MPOOL_SIZ_SIZE.

The dynamic range of this data type determines the maximum size of blocks that can be managed by the native QF event pool.

Definition at line 50 of file qmpool.h.

◆ QMPoolCtr

typedef uint8_t QMPoolCtr

The data type to store the block-counter based on the macro #QF_MPOOL_CTR_SIZE.

The dynamic range of this data type determines the maximum number of blocks that can be stored in the pool.

Definition at line 75 of file qmpool.h.

Function Documentation

◆ QMPool_init()

void QMPool_init ( QMPool *const  me,
void *const  poolSto,
uint_fast32_t  poolSize,
uint_fast16_t  blockSize 

Initializes the native QF memory pool

◆ QMPool_get()

void * QMPool_get ( QMPool *const  me,
uint_fast16_t const  margin,
uint_fast8_t const  qs_id 

Obtains a memory block from a memory pool.

◆ QMPool_put()

void QMPool_put ( QMPool *const  me,
void *  b,
uint_fast8_t const  qs_id 

Recycles a memory block back to a memory pool.
