expect_expectl

(no version information, might be only in CVS)

expect_expectl -- Waits until the output from a process matches one of the patterns, a specified time period has passed, or an EOF is seen

Opis

mixed expect_expectl ( resource expect, array cases, array &match )

Waits until the output from a process matches one of the patterns, a specified time period has passed, or an EOF is seen.

If match is provided, then it is filled with the result of search. The matched string can be found in match[0]. The match substrings (according to the parentheses) in the original pattern can be found in match[1], match[2], and so on, up to match[9] (the limitation of libexpect).

Parametry

expect

An Expect stream, previously opened with expect_popen().

cases

An array of expect cases. Each expect case is an indexed array, as described in the following table:
