NAME
cxOutputPortSharedXferGet
- query whether an output port supports shared geometry transfer
C SPECIFICATION
#include <cx/PortAccess.h>
int cxOutputPortSharedXferGet(int port)
FORTRAN SPECIFICATION
integer function cxOutputPortSharedXferGet(port)
integer port
PARAMETERS
-
port
-
IRIS Explorer output port identifier.
DESCRIPTION
This function indicates whether an output port is capable of
communicating geometry data in shared or socket mode. A non-zero
return value indicates shared transfer, while a zero return value
indicates socket transfer. A shared data transfer consumes fewer CPU
cycles and, since the geometry data will already reside in shared
memory, less memory.
If there are no output connections for this port or if all the port's
output connections involve shared memory communication, then the
geometry data for this port will be transcribed using shared memory.
Otherwise, the data will be transcribed in its entirety for socket
communication.
This function is intended primarily for internal use within the shared
geometry library.
