Your application may need to search files in sevaral directories, like
included does. For this purpose you can define and use your own
search paths. Create a search path like this:
Make a buffer for the path: create mypath 100 chars , \ maximum length (is checked) 0 , \ real len 100 chars allot \ space for path
You have the same functions for the forth search path in a generic version for different paths.
path+path-addr "dir" -- gforth ``path+''
adds a directory to the search path path-addr
path=path-addr "dir1|dir2|dir3" gforth ``path=''
makes complete new searchpath, seperator is |
.pathpath-addr -- gforth ``.path''
displays the contents of the search path path-addr
open-path-fileadr len path-addr -- fd adr1 len2 0 | ior gforth ``open-path-file''
looks in path path-addr for the file specified by adr len when found the resulting path and an open file descriptor is returned. If the file is not found ior is non zero
Go to the first, previous, next, last section, table of contents.
