RDM_RETCODE rdm_rdmAllocTFSWithMemBuf ( void * pMemBuf,
size_t memSize,
RDM_TFS * phTFS
)

#include <rdmrdmapi.h>

Allocate a TFS handle with an associated memory buffer.

Allocate the TFS handle and use the associated memory buffer instead of malloc for memory requests. If no memory buffer is specified and memSize is greater than 0 memSize will serve as the memory limit for the TFS, but memory will be obtained via calls to malloc.

Note
Until further notice the buffer provided and the size requested will be used for all TFS handles. This function should only be used once for allocating the first TFS handle. This semantic is subject to change.
Return values
sOKAY Normal, successful return.
eNOMEMORY Out of memory.
