Memsafe Boii

A simple header only library for handling memory in C/C++, without any possibility of memory leaks.

Usage

Just 4 simple functions:

• void* memsafe_boii_api__allocate(size_t mem_size) // Allocates memory

• void* memsafe_boii_api__reallocate(void* mem_ptr, size_t new_mem_size) // Re-Allocates memory

• void memsafe_boii_api__deallocate(void* mem_ptr) // Deallocates memory

• // Should be called at the end of program
  // Cleans up any un-freed memory
  void memsafe_boii__clean()

See test.c for example usage.

Testing

Compiling with DEBUG flag

gcc memsafe_boii.c test.c -DDEBUG -g -o test
