Typedef Documentation

QMPoolSize

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 56 of file qmpool.h.

QMPoolCtr

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.
