Detailed Description

Functions to check the state of the system memory pool.

Author: Jeff Hill

Definition in file osiPoolStatus.h.

Function Documentation

LIBCOM_API int epicsStdCall osiSufficentSpaceInPool ( size_t contiguousBlockSize )

Checks if a memory block of a specific size can be safely allocated.

The meaning of "safely allocated" is target-specific, some additional free space is usually necessary to keep the system running reliably. On vxWorks this returns True if at least 100000 bytes is free.

Note: This routine is called quite frequently by the IOC so an efficent implementation is important.

Parameters

contiguousBlockSize Block size to check.

Returns: True if the requested memory should be available.
