/*
|
|
* <poll.h> for the MontaukOS git port.
|
|
*
|
|
* git polls only descriptors it created itself with pipe() -- the stdout and
|
|
* stderr of a spawned sub-process (run-command.c's pump loop, sideband
|
|
* demultiplexing). MontaukOS has neither pipe() nor fork(), so those code
|
|
* paths are unreachable at runtime; this header exists so they compile, and
|
|
* the implementation reports every descriptor ready so that a caller which
|
|
* somehow gets here makes progress into the read() that reports the real
|
|
* error, instead of spinning in the poll loop forever.
|
|
*
|
|
* git's own compat/poll (NO_POLL=1) is not used: it is written against
|
|
* select() and <sys/select.h>, neither of which exists here.
|
|
*
|
|
* Implementation in montauk-compat.c.
