master: initial commit of mem_check ede7de7550d3243f98279b5bd69eba18748105fa Josiah_Mullins_E6440 2020-02-12 17:42:39
Commit 37dc1d6bdd6f4bf770d41146c6f614059b9f1d02 - mem_check.h: Added support for typecasting the declarations.
For example, the old style:
allocate_memory(data, size) -> data = malloc(size);
The new style:
allocate_memory(data, type, size) -> data = (type)malloc(size);
