Yes, It tracks whatever has been allocated. The search uses O(n) linear search, similar to insertion and deletion.

Running

Include in project. Please add -lrt. Included main.c is an example program demonstrating the functions

Compiling the example:

gcc -g -I include src/mapmanagement.c main.c -o main.out -lrc
./main.out

Functions

smalloc

void* smalloc(size_t size)

scalloc

void* scalloc(size_t size, int nmemb)

Sets the data values to zero, mandatorily

sfree

void sfree(void* ptr)

Only smalloc-ed or scalloc-ed variables are freed. This way, there is no:

1. Double frees
2. freeing null
3. freeing random locations

spurge

void spurge()

Clean all allocated memory. Implemented because it was possible.
