//
// Presentation :
// PclTar is a library that allow you to create a GNU TAR + GNU ZIP archive,
// to add files or directories, to extract all the archive or a part of it.
// So far tests show that the files generated by PclTar are readable by
// gzip tools and WinZip application.
//
// Description :
// See readme.txt (English & Français) and http://www.phpconcept.net
//
// Warning :
// This library and the associated files are non commercial, non professional
// work.
// It should not have unexpected results. However if any damage is caused by
// this software the author can not be responsible.
// The use of this software is at the risk of the user.

// Function : PclTarCreate()
// Description :
// Creates a new archive with name $p_tarname containing the files and/or
// directories indicated in $p_list. If the tar filename extension is
// ".tar", the file will not be compressed. If it is ".tar.gz" or ".tgz"
// it will be a gzip compressed tar archive.
// If you want to use an other extension, you must indicate the mode in
// $p_mode ("tar" or "tgz").
// $p_add_dir and $p_remove_dir give you the ability to store a path
// which is not the real path of the files.
// Parameters :
// $p_tarname : Name of an existing tar file
// $p_filelist : An array containing file or directory names, or
// a string containing one filename or directory name, or
// a string containing a list of filenames and/or directory
// names separated by spaces.
// $p_mode : "tar" for normal tar archive, "tgz" for gzipped tar archive,
// if $p_mode is not specified, it will be determined by the extension.
// $p_add_dir : Path to add in the filename path archived
// $p_remove_dir : Path to remove in the filename path archived
// Return Values :
// 1 on success, or an error code (see table at the beginning).

// Function : PclTarHandleHeader()
// Description :
// This function creates in the TAR $p_tar, the TAR header for the file
// $p_filename.
//
// 1. The informations needed to compose the header are recuperated and formatted
// 2. Two binary strings are composed for the first part of the header, before
// and after checksum field.
// 3. The checksum is calculated from the two binary strings
// 4. The header is write in the tar file (first binary string, binary string
// for checksum and last binary string).
// Parameters :
// $p_tar : a valid file descriptor, opened in write mode,
// $p_filename : The name of the file the header is for,
// $p_mode : The mode of the archive ("tar" or "tgz").
// $p_header : A pointer to a array where will be set the file properties
// Return Values :
// --------------------------------------------------------------------------------
