    Linux ACL  

    NAME

    acl_from_mode
    
     - create an ACL from file permission bits
    
     
    

    LIBRARY

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

    SYNOPSIS

       #include <sys/types.h>
       #include <acl/libacl.h>
    acl_t acl_from_mode (mode_t mode);
     

    DESCRIPTION

    The acl_from_mode ();
    function creates a minimal ACL that contains the three entries with tag types ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER, with permissions corresponding to the owner, group, and other permission bits of its argument mode  

    RETURN VALUE

    On success, this function returns a pointer to the working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.  

    ERRORS

    If any of the following conditions occur, the acl_from_mode ();
    function returns a value of (acl_t)NULL and sets errno to the corresponding value:

    Bq Er ENOMEM
    The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.

     

    STANDARDS

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