Function
GLibunix_open_pipe
since: 2.30
Description
Similar to the UNIX pipe()
call, but on modern systems like Linux
uses the pipe2()
system call, which atomically creates a pipe with
the configured flags. The only supported flag currently is
FD_CLOEXEC
. If for example you want to configure O_NONBLOCK
, that
must still be done separately with fcntl().
This function does not take O_CLOEXEC
, it takes FD_CLOEXEC
as if
for fcntl(); these are different on Linux/glibc.
Available since: 2.30
