Detailed Description

const variant of the struct iovec from system headers.

struct iovec is used for both, input and output operations. For being able to satisfy const semantics when writing data using an IO vector we need a variant of struct iovec that takes a const pointer. To do this we need a data structure that is equal to the system header's struct iovec with the exception of the const modifier for iov_base. It is casted to the original struct iovec internally when being passed to system calls, using the asIovec() helper.
