ridiculousfish	4b4bf541d1	Migrate more fd-concerned functions from wutil into fds ... Functions like wopen_cloexec have a new home in fds.cpp. This is in preparation for reworking how internal fds avoid conflict with user fds.	2021-02-05 17:58:08 -08:00
ridiculousfish	6588cf35f4	Move autoclose_pipes_t from io.h to fds.h	2021-02-05 17:58:08 -08:00
ridiculousfish	be9375e914	Migrate autoclose_fd_t to new file fds.h ... fds.h will centralize logic around working with file descriptors. In particular it will be the new home for logic around moving fds to high unused values, replacing the "avoid conflicts" logic.	2021-02-05 17:58:08 -08:00
