OpenBSD-4.6/gnu/usr.bin/lynx/src/LYLocal.c
/*
* Routines to manipulate the local filesystem.
* Written by: Rick Mallett, Carleton University
* Report problems to rmallett@ccs.carleton.ca
* Modified 18-Dec-95 David Trueman (david@cs.dal.ca):
* Added OK_PERMIT compilation option.
* Support replacement of compiled-in f)ull menu configuration via
* DIRED_MENU definitions in lynx.cfg, so that more than one menu
* can be driven by the same executable.
* Modified Oct-96 Klaus Weide (kweide@tezcat.com):
* Changed to use the library's HTList_* functions and macros for
* managing the list of tagged file URLs.
* Keep track of proper level of URL escaping, so that unusual filenames
* which contain #% etc. are handled properly (some HTUnEscapeSome()'s
* left in to be conservative, and to document where superfluous
* unescaping took place before).
* Dynamic memory instead of fixed length buffers in a few cases.
* Other minor changes to make things work as intended.
* Modified Jun-97 Klaus Weide (kweide@tezcat.com) & FM:
* Modified the code handling DIRED_MENU to do more careful
* checking of the selected file. In addition to "TAG", "FILE", and
* "DIR", DIRED_MENU definitions in lynx.cfg now also recognize LINK as
* a type. DIRED_MENU definitions with a type field of "LINK" are only
* used if the current selection is a symbolic link ("FILE" and "DIR"
* definitions are not used in that case). The default menu
* definitions have been updated to reflect this change, and to avoid
* the showing of menu items whose action would always fail - KW
* Cast all code into the Lynx programming style. - FM
