Function Documentation

vcl_string mbl_parse_block	(	vcl_istream &	afs,
		bool	open_already,
		const char *	comment
	)

Read a block of text from a stream.

This function will read through a stream, and store the text found to a string. The function terminates when it finds the closing brace.

The stream's fail bit will be set on error. Comment lines beginning with // will be stripped.

Parameters:

open_already

should be true if the client has already read the opening brace. If set to false and the first non-whitespace character is not an opening brace then that character will be left in the stream and "{} will be returned.

Returns:

the text including the opening and closing braces.

Parameters:

comment

Lines beginning with white space followed by this string will be ignored.

Exceptions:

mbl_exception_parse_block_parse_error

if unrecoverable parse error. Set to empty for no comment stripping.

The last character to be read from the stream.
