Using low-level functions when exploiting the C library
If you are using the libraries in an application that does not have a main()
function, you must re-implement some functions in the library.
CAUTION:
__rt_raise()
is essential if you are using the heap.
Note
If rand()
is called, srand()
must be
called first. This is done automatically during library initialization
but not when you avoid the library initialization.
