Do not use any of the interfaces documented here in new code. They are provided purely for compatibility with legacy application code.

All 8 of these functions are wrappers around the corresponding standard malloc(3), realloc(3), free(3), and strdup(3) functions.

These functions return the same type and value as the corresponding standard functions.
