-int fd2gio(int fd)
-.SH DESCRIPTION
-.I gopen
-takes a ReadWriter struct and creates a new instance of a gio fd.
-.I aux
-is an auxillary argument that may or may not be optional depending on how the gio stream is implemented.
-.I gclose
-closes a gio fd and frees any resources allocated to it.
-.I gseek
-changes the fd in a similar way to
-.IR seek (2).
-.I gread
-and
-.I gwrite
-are the gio equivalents to
-.IR pread (2)
-and
-.IR pwrite (2).
-They are functionally equivalent and have nearly the same usage.
-.I fd2gio
-takes a Plan 9 file descriptor and returns a gio descriptor made from that fd.
-.SH SOURCE
-.B /sys/src/libgio
-.SH NOTES
-The gio functions automatically lock the ReadWriter struct in use hopefully making things work better with
-.IR thread (2).
-.SH BUGS
-Things get interesting with
-.IR rfork (2)
-when you disable shared memory.
-.br
-The file descriptor table is poorly implemented.
-.br
-You cannot easily mix gio file descriptors with functions that want Plan 9 ones.
-.br
-
-.SH SEE ALSO
-.IR read (2),
-.IR seek (2),
-.IR open (2)
-.SH DIAGNOSTICS
-By default, no. Users can have their methods set 
-.I errstr,
-and
-.I gopen,
-.I gclose,
-.I gread,
-and
-.I gwrite
-will return -2 if a function pointer is nil.
-.SH HISTORY
-First appeared as part of
-.IR ngfs (8)
-in September 2015; imported into 9front February 2016.
