Hi All,
Does UV support opening another process's STDIN or STDOUT to a file descriptor? This
could solve a lot of interfacing problems for me. For those familiar with perl, this
functionality is provided by the open() function something like:
open(descriptor, "|externalcmd").
In UV, this would be equivalent to:
OPENSEQ "|externalcmd" TO DESCRIPTOR ...
or
OPENSEQ "externalcmd|" TO DESCRIPTOR ...
The '|' symbol in front of (or behind) the command determines whether the process is
opened for input or output.
You can then use WRITESEQ or READSEQ to communicate with the external unix/windows
program which reads its STDIN or writes to its STDOUT.
Similar functionality is already available in UV via the EXECUTE ... CAPTURING command
but its major drawback is that a new process is started with every EXECUTE and the
call to EXECUTE will block until the external process exits.
Thanks for any help.
Marco
