Detailed Description

processor heap statistics

This class is implementation of opt::procheap_stat option. The statistic counter implementation is based on atomic operations.

Template parameters:

INC_FENCE - memory fence for increment operation (default is release semantics)
READ_FENCE - memory fence for reading of statistic values (default is acquire semantics)

Member Function Documentation

atomic64u_t cds::memory::michael::procheap_atomic_stat::allocatedBytes ( ) const

inline

Get counter of allocated bytes.

This counter only counts the bytes allocated by Heap, OS allocation (large blocks) is not counted.

To get count of bytes allocated but not yet deallocated you should call

allocatedBytes() - deallocatedBytes()

atomic64u_t cds::memory::michael::procheap_atomic_stat::deallocatedBytes ( ) const

inline

Get counter of deallocated bytes.

This counter only counts the bytes allocated by Heap, OS allocation (large blocks) is not counted.unter of deallocated bytes

See allocatedBytes notes
