int Meta::MCommand::await

(

)

Wait for the command to exit and return status.

void Meta::MCommand::close

(

)

Close the command process.

void Meta::MCommand::matchError	(	const mstr &	re,
		mvec &	m
	)

Read from standard error until a regular expression has been matched.

Parameters:

re	The regular expression to match.
m	On output, the matched sub-expressions.

bool Meta::MCommand::matchError	(	const mstr &	re,
		mvec &	m,
		const mtime &	timeout
	)

Read from standard error until a regular expression has been matched with timeout.

Parameters:

re	The regular expression to match.
m	On output, the matched sub-expressions.
timeout	Return after timeout if output is not matched.

Returns:

true if successful.

void Meta::MCommand::matchOutput	(	const mstr &	re,
		mvec &	m
	)

Read from standard output until a regular expression has been matched.

Parameters:

re	The regular expression to match.
m	On output, the matched sub-expressions.

bool Meta::MCommand::matchOutput	(	const mstr &	re,
		mvec &	m,
		const mtime &	timeout
	)

Read from standard output until a regular expression has been matched with timeout.

Parameters:

re	The regular expression to match.
m	On output, the matched sub-expressions.
timeout	Return after timeout if output is not matched.

Returns:

true if successful.

int Meta::MCommand::processId

(

)

Returns:

the process id for the command.

bool Meta::MCommand::readError	(	mstr &	err,
		const mtime &	timeout
	)

Read standard error from the last time clearError() was called.

bool Meta::MCommand::readOutput	(	mstr &	out,
		const mtime &	timeout
	)

Read standard output from the last time clearOutput() was called.

int Meta::MCommand::status

(

)
