Declaration
int32_t mpiPlatformMemorySet64(MPIPlatform platform, void *dst, const void *src)
Required Header: stdmpi.h
Change History: Added in the 03.04.00
Description
mpiPlatformMemorySet64 sets (writes) 8 bytes of application memory (starting at address src) to platform memory (starting at address dst).
This function should be used to set/write any 64-bit data to the controller. This function can take up to one foreground cycle to complete. This function will take a platform lock blocking all other tasks from accessing the controller.
| platform | the handle to the controller's platform object. |
|---|---|
| dst | address of data (in host space) on the controller to be written. |
| src | address of host data storage area. Storage MUST be two words (64 bits). |
| Returns | |
|---|---|
| MPIMessageOK | |
| MPIMessageFATAL_ERROR | The platform type does not exist. |
Sample Code
fMPIInt64 newTargetPos; returnValue = mpiPlatformMemoryGet64(axis->platform,
&newTargetPos,
&axis->Axis->TC.CommandPosition); if (returnValue == MPIMessageOK) {
returnValue = mpiPlatformMemorySet64(axis->platform,
&axis->Axis->TC.TargetPosition, &newTargetPos);
}
