import core.sys.posix.sys.socket : msghdr, cmsghdr, iovec;

msg_iovlen, msg_controllen, cmsg_len is ulong for x86-64 in druntime.

in alpine musl, they are int, socklen_t(uint), socklen_t(uint).

Is this mismatch can cause problems is I use related api ?

Yes. Mismatch of types is a really bad error for c interaction.
