17. Access Control Lists > The ACL API

The ACL API

The POSIX.1e draft standard defined a large suite of functions and data structures for manipulating ACLs. Since they are so numerous, we won’t attempt to describe the details of all of these functions. Instead, we provide an overview of their usage and conclude with an example program.

Programs that use the ACL API should include <sys/acl.h>. It may also be necessary to include <acl/libacl.h> if the program makes use of various Linux extensions to the POSIX.1e draft standard. (A list of the Linux extensions is provided in the acl(5) manual page.) Programs using this API must be compiled with the -lacl option, in order to link against the libacl library.
