Function Description
sint32 ydatad_set_variable (const sint32 os32_DatapoolIndex, const sint32
os32_VariableListIndex,
const sint32
os32_VariableIndex,
const void * const
opv_Buffer,
const
uint32
ou32_NumberOfBytesToWrite)
This function verifies whether the indexed variable exists and that it is not locked by a write operation of another
process. The function writes the number of bytes from the buffer to the variable.
WARNING:
The variable list and data pool have to be initialized before. In addition the data pool has to be
loaded!
