Summary: std.stdio should have File.fdopen
--- Comment #0 from Per �ngstr�m <d-bugzi...@autark.se> 2010-11-09 01:24:31 PST
As far as I can tell, struct File in std.stdio does not have a direct way to
construct a File object from a low-level file descriptor, � la fdopen.
I ran into this issue when using fork and pipe to create a pipe between two
processes; having started a child process I wanted to parse the child's
standard output using high-level File functions, and for that purpose I wanted
to create a File object from a file descriptor.
After some head-scratching, I was finally able to work around the issue by
extern-declaring fdopen and using the sparsely documented File.wrapFile
function (which is labelled "unsafe") to construct a File object, but that was
inconvenient and obscure.
Implementing fdopen in File would make systems programming with Phobos easier.
