    Program crashing b/c of malloc, can someone please help?

    I created a function to do some security calculations....

    After completing these calculations, this function is suppose to return an array to main.

    I malloc'ed in the function like this... (its a 1d array)
    Code:
       tempResult=malloc(sizeof(int)*(hexLength*4));
       
       return tempResult;

    the functions declaration looks something like this (since im returning a 1d array):
    Code:
    int* NAME (PARAMETERS);
    Oh, and im 'receiving' the array that is returned into main by declaring a 1d integer array as follows:
    Code:
    int *xORresult
    and then setting xORresult array equal to the function call in main...

    Thanks in advance.
    Linklists use recursion to store what? ..... floats!

    There is no way we can tell from that. Try posting the smallest possible compilable example that demonstrates the problem.

    Post the smallest and simplest compilable program that demonstrates the problem. At the moment, we cannot check if your code snippet is correct, and then your example function declaration does not really say anything since you chose to replace the parameter list with a bogus PARAMETERS.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
