ER pget_mpf (ID mpfid, VP *p_blk);
ER ipget_mpf (ID mpfid, VP *p_blk);
This service call acquires the fixed-sized memory block from the fixed-sized memory pool specified by parameter mpfid and stores the start address in the area specified by parameter p_blk.
If a fixed-sized memory block could not be acquired from the target fixed-sized memory pool (no available fixed-sized memory blocks exist) when this service call is issued, fixed-sized memory block acquisition processing is not performed but "E_TMOUT" is returned.
Note 2 The boundary alignment for the memory blocks acquired is 1. If memory blocks need to be acquired with a larger boundary alignment than that, observe the following:
- Set The size of the fixed-sized memory block (siz_block) in Fixed-sized Memory Pool Information (memorypool[]) to multiple of the desired boundary alignment.
- Specify unique section name to the Section name assigned to the memory pool area (section) in Fixed-sized Memory Pool Information (memorypool[]) and locate the section to the address of the desired boundary alignment when linking.
