PARAMETERS
Message buffer identifier.
DESCRIPTION
A wait identifier is part of a message (like the source,
destination, tag and body).
It is used to match a reply to the corresponding request.
The default wait ID for a message is zero (none).
pvm_getmwid returns the wait ID associated with a message buffer,
or a negative error code.
pvm_setmwid assigns a new wait ID to a message buffer.
It returns PvmOk unless an error occurs.
EXAMPLES
int src, tag;
pvm_recv(-1, -1);
/* ... process, compose reply message */
pvm_setmwid(pvm_getsbuf(), pvm_getmwid(pvm_getrbuf()));
pvm_bufinfo(pvm_getrbuf(), (int *)0, &tag, &src);
pvm_send(src, tag);
ERRORS
The following error conditions can be returned by
pvm_getmwid or pvm_setmwid:
Invalid value for bufid argument.
Message buffer bufid doesn't exist.
