etags-goto-tag-location

etags-goto-tag-location is a compiled Lisp function in `etags.el'.

(etags-goto-tag-location TAG-INFO)

Go to location of tag specified by TAG-INFO.
TAG-INFO is a cons (TEXT LINE . POSITION).
TEXT is the initial part of a line containing the tag.
LINE is the line number.
POSITION is the (one-based) char position of TEXT within the file.

If TEXT is t, it means the tag refers to exactly LINE or POSITION,
whichever is present, LINE having preference, no searching.
Either LINE or POSITION can be nil. POSITION is used if present.

If the tag isn't exactly at the given position, then look near that
position using a search window that expands progressively until it
hits the start of file.
