using standard datatypes in NIDAQmx functions

[KJ]

I use NIDAQmx 8.6 with LabWindows 7.1. Can I use in NIDAQmx- functions the standard datatypes instead of the NIDAQmx datatypes?

For example 'unsigned char' instead of 'uInt8', 'long' instead of 'TaskHandle'.

I have seen in 'NIDAQmx.h' that NIDAQmx datatypes anyway are derivates from the standard datatypes.

Imho you can use the standard types, as long as they are equivalent. The advantage of using the predefined special datatypes as found in DAQ etc is that sometimes such definitions may change (i.e. due to porting from 32 bit to 64 bit applications). In such cases your code may remain untouched, as NI should take care of a suitable, adapted type definition.

Note: the data type of TaskHandle changed from 'uInt32' to 'void*' with DAQmx 9.0 (or 9.1? I skipped 9.0).
