execl(3) and its variants use a sentinel to terminate the variadic argument list, in the form of a null pointer constant of type pointer to char. POSIX mandates that NULL is a null pointer constant of type pointer to void, which is not of an equivalent type to that required by execl(3) and its variants, resulting in undefined behaviour. This commit casts all such instances of NULL to pointer to char type. For consistency, it also adds const-qualification to any such instances which had already been casted, and were not const-qualified. |
