lq-text: LQT_UnpackAndOpen

API int LQT_UnpackAndOpen (db, FileName) t_LQTEXT_Database *db; char *FileName;

Purpose

Tries to open the named file, using compress or gunzip as necessary. Can append a .Z or .gz to the file name. Currently, LQT_UnpackAndOpen makes a copy of a file if necessary; a future version may create a pipe, and the interface will change.

Returns

an open file descriptor on success;
-1 if the file couldn't be opened.
