#define PARSE_STRICT   false

#define PARSE_VERBATIM_STRINGS   PARSE_STRICT

#define PARSE_COMMENTED_LINES   !PARSE_STRICT

#define PARSE_STRING_CONTINUATION   true

#define BEFORE_POSITION   true

Generates a string describing the line position of the location.

The string is formatted as:

"<b> at</b>|<b>before character </b><i>C</i> of line <i>L</i>\\n</b>"

where the choice of "at" or "before" is conditional on the before argument, and L is the line number and C is the character offset in that line corresponding to the location in the input stream.

If the Parser is not using a Line_Count_Filter, or the location is invalid, then an empty string is returned.

Parameters:

before	true if the description starts with "before"; otherwise the string starts with "at".
location	The Location in the input stream for which to find a line position.

Returns:

A string describing the line position, or the empty string.
