Indicate how many parts from the ctp->iov structure to return to the client
#include <sys/resmgr.h>
#define _RESMGR_NPARTS( int num ) ...
- num
- The number of parts that you want the resource manager library to return
to the client.
None.
The macro _RESMGR_NPARTS() indicates
to the resource manager library that it should return
num parts from the
ctp->iov structure (see
resmgr_context_t)
to the client.
In effect, the library does the following:
MsgReply( ctp->rcvid, ctp->status, ctp->iov, num ).
The negative of num (to distinguish the number from error codes
that the handler functions might return).
