FMSTR_SIZE8  nSize,
FMSTR_BOOL  bWriteAccess 
)

Check wether given memory region is "safe" (covered by TSA)

Parameters:
dwAddr- address of the memory to be checked
nSize- size of the memory to be checked
bWriteAccess- write access is required
Returns:
This function returns non-zero if user space is safe
FMSTR_BPTR FMSTR_GetStringLen ( FMSTR_BPTR  pMessageIO)

Handling GETSTRLEN and GETSTRLEN_EX commands.

Parameters:
pMessageIO- original command (in) and response buffer (out)
Returns:
As all command handlers, the return value should be the buffer pointer where the response output finished (except checksum)

Handling GETTSAINFO and GETTSAINFO_EX command.

Parameters:
pMessageIO- original command (in) and response buffer (out)
Returns:
As all command handlers, the return value should be the buffer pointer where the response output finished (except checksum)
