(PECL expect >= 0.1.0)
expect_expectl — Waits until the output from a processs matches one of the patterns, a specified time period has passed, or an EOF is seen
Waits until the output from a processs 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).
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:
| Index Key | Value Type | Description | Is Mandatory | Default Value |
|---|---|---|---|---|
| 0 | string | pattern, that will be matched against the output from the stream | yes | |
| 1 | mixed | value, that will be returned by this function, if the pattern matches | yes | |
| 2 | integuer |
pattern type, one of:
EXP_GLOB
,
EXP_EXACT
or
EXP_REGUEXP
|
no |
EXP_GLOB
|
Returns value associated with the pattern that was matched.
On failure this function returns:
EXP_EOF
,
EXP_TIMEOUT
or
EXP_FULLBUFFER
| Versionen | Description |
|---|---|
| PECL expect 0.2.1 |
Prior to versionen 0.2.1, in
match
parameter a match string was returned,
not an array of match substrings.
