[GNU PDF Library]

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY.

A new Flyspray task has been opened.  Details are below. 

User who did this - Aleksander Morgado (aleksander) 

Attached to Project - GNU PDF Library
Summary - New FS module function: pdf_fsys_build_path()
Task Type - Sporadic Task
Category - Filesystem Module
Status - NEXT
Assigned To - 
Operating System - All
Severity - Low
Priority - Low
Reported Version - START
Due in Version - BASE-LAYER-0
Due Date - Undecided
Details - The idea is to have a method equivalent to GLib's g_build_filename()
http://library.gnome.org/devel/glib/unstable/glib-Miscellaneous-Utility-Functions.html#g-build-filename

When working with the FS interface, sometimes you may want to build local paths, for 
example after getting the list of files in a given directory, if you want to have the whole 
path of each children you need to concatenate <directory> + <dir-separator> + 
filename. As the dir-separator character depends on the OS in the disk-FS module, it makes 
sense to put the new method in the FS interface.

The API of the new method (with a variable number of arguments) could then be:
pdf_status_t
pdf_fsys_build_path (pdf_text_t *output, pdf_text_t first_element, ...);

If PDF_OK returned, `output' will be a newly allocated pdf_text_t object with 
the proper concatenations.

Example:
pdf_text_t full_path = NULL;
pdf_text_t filename = NULL;
pdf_text_t parent_path = get_current_dir_as_text (); /* example */

pdf_text_new_from_from_unicode ("filename.txt",
                               strlen ("filename.txt"),
                               PDF_TEXT_UTF8,
                               &filename);

pdf_fsys_build_path (&full_path,
                    parent_dir,
                    filename);
