[SOLVED] Q_strcmp, Q_stricmp, etc...
« on: July 04, 2008, 02:37:05 am »
Hello everyone.

I've seen various functions in the SVN with names like Q_strcmp, Q_stricmp, Q_strncmp, Q_strncpy, etc. Can someone please tell me what these do and how to use them?

exactly the same thing as their crt equivalents (in fact if building shared objects they ARE the crt versions)

I'm sorry, but could you rephrase that? So a non-pro like myself can understand?

google "c strcmp" "c strncmp" etc.

Each of those (minus the Q_ prefix) is a function in C. The versions that the VMs use will behave the same way, so far as you're concerned.

That is true of the functions in bg_lib.c (which have the same names as the CRT equivalent). It is not true of the Q_* functions.

Virtually all of them are defined in src/qcommon/q_shared.c, and most of them are actually pretty simple.

The Q_ is short for Quake, and ensures that the functions used are the ones in q_shared.c rather than in system libraries, for consistency.

Ahhh. Well, I googled "c strcmp" and it was very helpful. Thanks all.

They are all string manipulating/comparing functions.
