Is this a built in pspsdk function to get the current amount of free RAM so that I get an idea of how much memory my program is using on PSP?

If you do a search you will turn up some stuff.

Somebody has written some code to find both out for you, and there are tricks you can do for raw free ram. (largest available block is more difficult but the code is there too).

I don't take credit for this, and I forgot the name of the guy who wrote it. If you do a search, you will find the origional post containing this code. This bad boy works like a charm, and has helped me out something fierce.

float GetFreeRam()
{
float ram = 0;
int i = 0;
int ramAdd[320];

for(i=0; i<320; i++)
{
ramAdd[i] = malloc(100000);
if(ramAdd[i] == 0) //malloc failed
{
ram = (float) i;
int z = 0;
for(z=0; z<i; z++)
{
free(ramAdd[z]);
}
break;
}
}
return(ram/10);
}

The code pasted above works, and I used it for a while, but I replaced it for this.
It works, and returns bytes instead of megabytes.
