Function Documentation

LIBCOM_API int epicsStdCall osiSufficentSpaceInPool

(

size_t

contiguousBlockSize

)

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 efficient implementation is important.

Parameters

contiguousBlockSize

Block size to check.

Returns

True if the requested memory should be available.
