NAME

     acl_entries — return the number of entries in an ACL

LIBRARY

     Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

     #include <sys/types.h>
     #include <acl/libacl.h>

     int
     acl_entries(acl_t acl);

DESCRIPTION

     The acl_entries() function returns the number of ACL entries that are contained in the ACL
     referred to by the argument acl.

RETURN VALUE

     The acl_entries() function returns the number of entries in acl if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_entries() function returns -1 and sets
     errno to the corresponding value:

     [EINVAL]           The argument acl is not a valid pointer to an ACL.

STANDARDS

     This is a non-portable, Linux specific extension to the ACL manipulation functions defined
     in IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned).
