fdwalk

[Markus Teich <mteich google com>]

Heyho,

I discovered you have a fdwalk implementation in glib/gspawn.c which is not exported as a usable symbol. Is there any reason for this? If not, I'd suggest exporting that symbol and maybe even another wrapper that takes a list of FDs to keep open instead of the callback pointer and closes all other ones. Closing all fds except some specific ones is a common pattern before exec()ing.
