ER pget_mpl (ID mplid, UINT blksz, VP *p_blk);
ER ipget_mpl (ID mplid, UINT blksz, VP *p_blk);
This service call acquires a variable-size memory block of the size specified by parameter blksz from the variable-size memory pool specified by parameter mplid, and stores its start address into the area specified by parameter p_blk.
If no variable-size memory blocks could be acquired from the target variable-size memory pool (no successive areas equivalent to the requested size were available) when this service call is issued, this service call does not acquire variable-size memory block but returns "E_TMOUT".
Note 3 The alignment number of memory blocks changes with creation method of the variable-sized memory pool.
- Created by system configuration file
The alignment number is 1. To enlarge the alignment number to 4, specify unique section to Section name assigned to the memory pool area (mpl_section) in Variable-sized Memory Pool Information (variable_memorypool[]) and locate the section to 4-bytes boundary address when linking.
