    NAME

    
    
    acl_set_fd
    
     
    acl_set_fd_np
    
     
    acl_set_file
    
     
    acl_set_link_np
    
     - set an ACL for a file
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <sys/types.h>
       #include <sys/acl.h>
    int acl_set_fd (int fd acl_t acl);
    int acl_set_fd_np (int fd acl_t acl acl_type_t type);
    int acl_set_file (const char *path_p acl_type_t type acl_t acl);
    int acl_set_link_np (const char *path_p acl_type_t type acl_t acl);
     

    DESCRIPTION

    The acl_set_fd (,);
    acl_set_fd_np (,);
    acl_set_file (,);
    and acl_set_link_np ();
    each associate an ACL with an object referred to by fd or path_p The acl_set_fd_np ();
    and acl_set_link_np ();
    functions are not POSIX.1e calls. The acl_set_fd ();
    function allows only the setting of ACLs of type ACL_TYPE_ACCESS where as acl_set_fd_np ();
    allows the setting of ACLs of any type. The acl_set_link_np ();
    function acts on a symlink rather than its target, if the target of the path is a symlink.  

    IMPLEMENTATION NOTES

    Fx Ns 's support for POSIX.1e interfaces and features is still under development at this time.  

    RETURN VALUES

    Rv -std  

    ERRORS

    If any of the following conditions occur, these functions shall return -1 and set errno to the corresponding value:

    Bq Er EACCES
    Search permission is denied for a component of the path prefix, or the object exists and the process does not have appropriate access rights.
    Bq Er EBADF
    The fd argument is not a valid file descriptor.
    Bq Er EINVAL
    Argument acl does not point to a valid ACL for this object, or the ACL type specified in type is invalid for this object, or both.
    Bq Er ENAMETOOLONG
    A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
    Bq Er ENOENT
    The named object does not exist, or the path_p argument points to an empty string.
    Bq Er ENOMEM
    Insufficient memory available to fulfill request.
    Bq Er ENOSPC
    The directory or file system that would contain the new ACL cannot be extended, or the file system is out of file allocation resources.
    Bq Er EOPNOTSUPP
    The file system does not support ACL retrieval.
    Bq Er EROFS
    This function requires modification of a file system which is currently read-only.

    STANDARDS

    POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the Fx POSIX.1e implementation page for more information.  

    HISTORY

    POSIX.1e support was introduced in Fx 4.0 , and development continues.
