    NAME

    acl_create_entry
    
     - create a new ACL entry
    
     
    

    LIBRARY

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

    SYNOPSIS

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

    DESCRIPTION

    The acl_create_entry ();
    function creates a new ACL entry in the ACL pointed to by the contents of the pointer argument acl_p On success, the function returns a descriptor for the new ACL entry via entry_p

    This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free3 with (void*)*acl_p as an argument. If the ACL working storage cannot be increased in the current location, then the working storage for the ACL pointed to by acl_p may be relocated and the previous working storage is released. A pointer to the new working storage is returned via acl_p

    The components of the new ACL entry are initialized in the following ways: the ACL tag type component contains ACL_UNDEFINED_TAG, the qualifier component contains ACL_UNDEFINED_ID, and the set of permissions has no permissions enabled. Any existing ACL entry descriptors that refer to entries in the ACL continue to refer to those entries.  

    RETURN VALUE

    Rv -std acl_create_entry  

    ERRORS

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

    Bq Er EINVAL
    The argument acl_p is not a valid pointer to an ACL.
    Bq Er ENOMEM
    The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
