CCPU_WriteSharedMemory
Writes data to the shared memory of a MELIPC.
Format
short CCPU_WriteSharedMemory(unsigned long ulOffset, unsigned long ulSize, unsigned char* pucDataBuf)
Argument
Argument Name
ulOffset Offset
ulSize Data size
pucDataBuf Data storage destination
Description
• Reads data of the data size (ulSize) from an address moved by the amount of the offset (ulOffset) from the start of the
shared memory, and then stores it in the data storage destination (pusDataBuf).
• When "0" was specified for the data size (ulSize), a memory size specification error occurs.
• The size of the shared memory area is 256 MB (268,435,456 bytes (10000000H)). Specify the offset (ulOffset) and data
size (ulSize) so that data in the shared memory area is written.
