These service calls store the detailed information (ID number of the task at the head of the wait queue, total size of free memory blocks, etc.) of the variable-size memory pool specified by parameter
mplid into the area specified by parameter
pk_rmpl.
-
wtskid
Stores whether a task is queued to the variable-size memory pool wait queue.
Value: ID number of the task at the head of the wait queue
-
fmplsz
Stores the total size of free memory blocks (in bytes).
-
fblksz
Stores the maximum memory block size available (in bytes).
