Thread: [Error] Id returned 1 exit status

I keep getting this "[Error] Id returned 1 exit status" when I'm using some specific functions and I can't figure out why. Here's the last piece of code that's been giving me this error.

Code:

#include <stdio.h>
#include <malloc.h>

main(){
    printf("Memory available: %u\n", _memavl());
}

It also says "Undefined reference to memavl" It's probably something simple and I'm missing it. It also gave me something like this when I tried using "cprintf" too. I tried checking to see if the program is running on the background and it's not. Thanks for your help.

Where have you implemented the function?

That's the whole code, actually. I included the header file and tried to use it in main block of my program. I'm a beginner so I'm just testing functions to figure out how they work. It also crashes when I try:

Code:

#include <stdio.h>#include <malloc.h>
main(){
    char *x="Testing";
    printf("%u",_msize(x));
}

I don't know if it's related.

I'm using Dev C++ and yes, you are right. I found this old book that was published in 1991 and I thought it would be a good idea to start learning how to code in C. Are there better functions to get the amount of the available memory today?

God... I guess this is the worst part of trying to teach these things to yourself alone. Thanks for the replies. I'll look it up on the internet to get more info about memory usage and try to find out a less outdated compilers and sources.
