    NAME

    
    
    acl_get_entry
    
     - retrieve an ACL entry from an ACL
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <sys/types.h>
       #include <sys/acl.h>
    int acl_get_entry (acl_t acl int entry_id acl_entry_t *entry_p);
     

    DESCRIPTION

    The acl_get_entry ();
    function is a POSIX.1e call that retrieves a descriptor for an ACL entry specified by the argument Fa entry_d within the ACL indicated by the argument Fa acl .

    If the value of Fa entry_id is ACL_FIRST_ENTRY then the function will return in Fa entry_p a descriptor for the first ACL entry within Fa acl . If a call is made to acl_get_entry ();
    with Fa entry_id set to ACL_NEXT_ENTRY when there has not been either an initial successful call to acl_get_entry (,);
    or a previous successful call to acl_create_entry (,);
    acl_delete_entry (,);
    acl_dup (,);
    acl_from_text (,);
    acl_get_fd (,);
    acl_get_file (,);
    acl_set_fd (,);
    acl_set_file (,);
    or acl_valid (,);
    then the result is unspecified.  

    RETURN VALUES

    If the acl_get_entry ();
    function successfully obtains an ACL entry, a value of 1 is returned. If the ACL has no ACL entries, the acl_get_entry ();
    returns a value of 0. If the value of Fa entry_id is ACL_NEXT_ENTRY and the last ACL entry in the ACL has already been returned by a previous call to acl_get_entry (,);
    a value of 0 will be returned until a successful call with Fa entry_id of ACL_FIRST_ENTRY is made. Otherwise, a value of -1 will be returned and the global variable errno will be set to indicate the error.  

    ERRORS

    The acl_get_entry ();
    fails if:

    Bq Er EINVAL
    Argument Fa acl does not point to a valid ACL. Argument Fa entry_id is neither ACL_FIRST_ENTRY nor ACL_NEXT_ENTRY
