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!
