Example
// Global module
sint32 s32_DataPoolIndex;
sint32 s32_ListIndex;
sint32 s32_VarIndex;
float32 f32_Value = 5;
sint32 s32_Retval;
s32_DataPoolIndex = ydatad_get_datapool_index ("MyDatapool")
s32_ListIndex = ydatad_get_list_index (s32_DataPoolIndex , "GPSDates");
s32_VarIndex = ydatad_get_variable_index (s32_DataPoolIndex, s32_ListIndex , "Longitude");
s32_Retval = ydatad_set_variable (s32_DataPoolIndex, s32_ListIndex, s32_VarIndex,
&f32_Value, sizeof(float32));
if (s32_Retval == C_NO_ERR)

// Go on
}
7.3.5.4.8 ydatad_get_variable
Function Description
sint32 ydatad_get_variable (const sint32 os32_DatapoolIndex, const sint32
os32_VariableListIndex, const sint32 os32_VariableIndex, const void * const opv_Buffer, uint32
const ou32_SizeOfBuffer)
The function verifies, whether the indexed variable exists and reads the maximum number of bytes into the
buffer of the variable memory of opv_Buffer.
