You are confusing xHarbour code and C code. For me the problem is in the
PlaySound() function that I don't know what it does.

.... the Newsgroup they are asking on. How are these variables defined, made 'LOCAL' in C? In the function definition, right?

https://www.geeksforgeeks.org/variables-in-c/
.... looks like "STATIC" is a better choice, and lose the 'release' suggestion.

Could be a non-trivial memory leak there too, sure. Sound files are often large. Maybe log free memory before and after each call?

They are already defined as the C equivalent of LOCAL. There is no
memory leak in that code. The only place where it could be is, as I
alredy wrote, the unknown function PlaySound().

Agreed on PlaySound. I find a thread on MSN that cite it (presumably built-in language function) as 1 Meg with every call, but might be out-of-date.

Thanks for your persistence / tolerance.

Hi All and thanks so much for the help
I did not have a chance yet to test

I believe playSound took over the Microsoft legacy sndPlaySound

It is entirely possible it is just a wrapper problem, since PlaySound is also a WIN32 control. Should not be a leak in the Windoze code itself...
