Free memory allocated from a function

[ne0h]

Hi,
I'm still working on Xplora, but I've see that the memory is not completely free when returning from the Text editor, so there's a solution to free all the memory allocated by this function or I can only try to improve the code to free the allocated memory?

Thanks in advance

Improve the code and free any pointers you have allocated. Don't forget to free images too.

Yes, I know that this is the best solution but I'll see if ther's another possibility...

I've a newbie question, is better to do many if\else if or a switch\case loop? ( for execution speed performance )

[Pirata Nervo]

it is better to use switch (when you can) instead of many if's. It makes your code neat and clear. I don't know about speed but it might be the same.
Remember that if's can make things VERY slow. Example:

Code: Select all

char charv[200];
sprintf(charv, "my name is blablabla");
if (strlen(charv) >= 100 && strcmp(charv, "my name is blablabla") == 0)
{
  // etc
}

It executes 2 functions:
strlen
strcmp

the actual if does not slow down but its conditions can slow down your program.

Ok, thanks!

Thats pretty much the same as running two if statements in the assembly.

I know but we were not talking about that, we were talking about the "slow down".

Exactly...
The number of conditions (n) in a single if can also be represented as n if statements.

The actual if CAN cause slowdowns, as it is an instruction, but its so small.

Your example is terrible btw.

[Pirata Nervo]

Then why is my example terrible?
