I have a variable length array that I am trying to pass into a function. The function will shift the first value off and return it, and move the remaining values over to fill in the missing spot, putting, let's say, a -1 in the newly opened spot.
I have no problem passing an array declared like so:
int framelist[128];
shift(framelist);
However, I would like to be able to use a VLA declared in this manner:
int *framelist;
framelist = malloc(size * sizeof(int));
shift(framelist);
I can populate the arrays the same way outside the function call without issue, but as soon as I pass them into the shift function, the one declared in the first case works fine, but the one in the second case immediately gives a segmentation fault.
Here is the code for the queue function, which doesn't do anything except try to grab the value from the first part of the array...
int shift(int array[])
{
int value = array[0];
return value;
}
Any ideas why it won't accept the VLA?
I'm still new to C, so if I am doing something fundamentally wrong, let me know.
