Description Michael Kerrisk 2006-03-12 18:53:01 UTC 
In <bits/socket.h>, the msg_controllen field of the msghdr 
field is typed as size_t (perhaps because the definition was
based on the kernel_size_t used in the Linux kernel).  
However, POSIX reguires this field to be typed as socklen_t,
and glibc should probably do this.

Tell this to the kernel people.  They define the data structure.  It's not
possible to use socklen_t because it  has a different size on 64-bit platforms.

The referrent of the second 'it' in that sentence was unclear.  I'm 
assuming 'it' == sizeof(__kernel_size_t), right?

Cheers,
