Hi all

Why SDL\_malloc and SDL\_free not in SDL 2.0 API by Name page?

SDL 2.0 API by Name: [http://wiki.libsdl.org/moin.cgi/CategoryAPI](http://wiki.libsdl.org/moin.cgi/CategoryAPI)

Are these two functions supposed NOT to be used by SDL users?

Best regards  
Unga

I wouldn’t trust much the wiki since it’s extremely outdated compared  
to the current version. It really needs some maintenance. Check the  
relevant header files to make sure.

Which reminds me: obviously the header files imply Doxygen is  
supported, but I have no idea how to generate the Doxygen files.  
Assuming Doxygen is installed, is there any special step to make the  
docs or just running “make” should do it and I failed to look at the  
correct place?

doxygen include/doxyfile

and the documentation was correctly generated.

> By looking at the definitions of SDL\_malloc and SDL\_free in SDL\_stdinc.h, its just a simulation of Standard C Library malloc and free. It is obvious its perfectly alright for public use. I should have done bit more home work 🙂
