FRXAN Prolog
Name : HCPFRXAN Description: Storage pool statistics DSECT : FRXAN FUNCTION : Maps the storage pool statistics for the storage pools maintained by HCPFRX. CREATED BY : N/A (statically defined within HCPFRX) DELETED BY : N/A SERIALIZED : All HCPFRX data areas, including this anchor block, are serialised by TSGET on the flag HCPFRXLK. NOTES : This block maps the address and length of the fast-fit memory pool, the address and length of the "root" node and statistics. It can be used to map the HCPFRXFP (primary pool) and HCPFRXFS (secondary pool) information. See the prologue of HCPFRX for a more detailed description.
