isatty() is used within Postgres code already (for example, pg_upgrade/util.c). However, it seems that on Windows isatty() is deprecated and it is recommended to use _isatty(). Moreover, on Windows it can give false positive result [1], if I'm not mistaken: > The _isatty function determines whether fd is associated with a character > device (a terminal, console, printer, or serial port). 1 - https://msdn.microsoft.com/en-us/library/f4s0ddew(v=vs.140).aspx -- Arthur Zakirov Postgres Professional: http://www.postgrespro.com Russian Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
