◆ osiSufficentSpaceInPool()
| 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 efficent implementation is important.
- Parameters
-
contiguousBlockSize Block size to check.
- Returns
- True if the requested memory should be available.
