initialize msghdr in a compatible manner
|
|
|
|
msghdr stuct from socket.h is not same between musl and glibc
|
|
where musl claims to be more posix compliant where as glibc seems
|
|
to fill whats needed for linux sizewise and chooses long enough types
|
|
which maybe questionable, therefore constructing a structure with explicit
|
|
constructor is not going to work correctly for musl and glibc at same time
|
|
|
|
see
|
|
https://git.musl-libc.org/cgit/musl/commit/arch/x86_64/bits/socket.h?id=7168790763cdeb794df52be6e3b39fbb021c5a64
|

|
|
This fix initialized the struct to 0 first and then sets the struct elements
|
|
by name, so we dont have to hard code the positions of elements when initializing
|
|
structure
