This is minimalistic memory manager. I have two primary target for this project: detect memory leaks into my projects.

So, I had wrote simple memory allocator in MS-DOS style.

Also, this project could be used for embeded systems.

Here is example.c. This code have a problem into test_bad() and you will see memory dump. Memory dump test_ok() will be empty.

If you don't want have a debug info - just remove GC_DUMP() call and you will have small and sweet memory allocator into your project. :)

    #include "safegc.h"

    void test_ok() {
        char *str = GC_MALLOC(126);
        GC_FREE(str);
        GC_DUMP();
    }

    void test_bad() {
        char *str = GC_MALLOC(126);
        GC_DUMP();
    }

    int main() {
        GC_INIT(1024 * 64);
        test_ok();
        test_bad();
        GC_DONE();
        return 0;
    }

To start use safegc you should include safegc.h. If you want use safegc (or switch to system calls) - you should pass complier option:

$ gcc -DINTERNAL_GC ...

If you dont pass INTERNAL_GC option - your code will work with system's malloc / realloc / free.

Here is a few predefined "macros" from safegc.h:

GC_INIT(size_t) - Allocate system memory bytes for safegc.

GC_MALLOC(size_t) - Allocate internal memory. Return *void

GC_REALLOC(void *, size_t) - Realloc new size of internal memory. Return *void.

GC_FREE(void *) - Free internal memory.

GC_DONE() - Destroy allocated system memory. I shoud call only in end of your programm.

GC_DUMP() - Show internal memory state (if something has been allocated). You may not use it.

$ make

or

$ gcc -DINTERNAL_GC example.c safegc.c -o example_gc
$ gcc example.c safegc.c -o example

NONE

I maintain this project in my free time, if it helped you please support my work via Bitcoins, thanks a lot!
