Declaration

int32_t mpiCaptureMemoryGet(MPICapture  capture,
                         void        *dst,
                         const void  *src,
                         int32_t        count)

Required Header: capture.h
Change History: Modified in the 03.03.00

Description

mpiCaptureMemoryGet copies count bytes of a Capture object's (capture) memory (starting at address src) and writes them into application memory (starting at address dst).

Return Values
MPIMessageOK

Sample Code 


/* captureDataGet(...) demonstrates how to read sample counter 
of a capture object. mpiCaptureMemory(...) obtains the capture
control memory pointer. The pointer's address is then passed
into mpiCaptureMemoryGet(...) to obtain the sampleCounter value.
Note: MPIXmpCapture *memory must be casted as (void *) in
mpiCaptureMemory.
*/
