NAME

archive_entry_clear archive_entry_clone archive_entry_free archive_entry_new - functions for managing archive entry descriptions  

LIBRARY

Streaming Archive Library (libarchive, -larchive)  

SYNOPSIS

In archive_entry.h Ft struct archive_entry * Fn archive_entry_clear struct archive_entry * Ft struct archive_entry * Fn archive_entry_clone struct archive_entry * Ft void Fn archive_entry_free struct archive_entry * Ft struct archive_entry * Fn archive_entry_new void  

DESCRIPTION

These functions create and manipulate data objects that represent entries within an archive. You can think of a struct archive_entry as a heavy-duty version of struct stat it includes everything from struct stat plus associated pathname, textual group and user names, etc. These objects are used by libarchive(3) to represent the metadata associated with a particular entry in an archive.  

Create and Destroy

There are functions to allocate, destroy, clear, and copy archive_entry objects:

Fn archive_entry_clear

Erases the object, resetting all internal fields to the same state as a newly-created object. This is provided to allow you to quickly recycle objects without thrashing the heap.

Fn archive_entry_clone

A deep copy operation; all text fields are duplicated.

Fn archive_entry_free

Releases the struct archive_entry object.

Fn archive_entry_new

Allocate and return a blank struct archive_entry object.

 

Function groups

Due to high number of functions, the accessor functions can be found in man pages grouped by the purpose.

archive_entry_acl3

Access Control List manipulation

archive_entry_paths3

Path name manipulation

archive_entry_perms3

User, group and mode manipulation

archive_entry_stat3

Functions not in the other groups and copying to/from Vt struct stat .

archive_entry_time3

Time field manipulation

Most of the functions set or read entries in an object. Such functions have one of the following forms:

Fn archive_entry_set_XXXX

Stores the provided data in the object. In particular, for strings, the pointer is stored, not the referenced string.

Fn archive_entry_copy_XXXX

As above, except that the referenced data is copied into the object.

Fn archive_entry_XXXX

Returns the specified data. In the case of strings, a const-qualified pointer to the string is returned.

String data can be set or accessed as wide character strings or normal char strings. The functions that use wide character strings are suffixed with _w Note that these are different representations of the same data: For example, if you store a narrow string and read the corresponding wide string, the object will transparently convert formats using the current locale. Similarly, if you store a wide string and then store a narrow string for the same data, the previously-set wide string will be discarded in favor of the new data.
