"g" prefix on many DAQmx variable names

[DrScience]

I am new to DAQmx.  As I look through example programs, I find many variables have a 'g' prefix, such as in "gTaskHandle".  Can anyone explain why this prefix is used?  There is also the use of a "gh" prefix.  What meaning does that have?

Hi,

That 'g' probably means global.

This is a naming convention used by the coder of those samples.

I myself use a similar way to identify my variables within the body of the code.

I find it useful, too.
