t6peek_attr(3N)

NAME
     t6peek_attr, t6last_attr - examine the security attributes on the next or
     previous byte of data

SYNOPSIS
     cc [ flags ... ] file -lt6

     #include <sys/t6attrs.h>

     int t6peek_attr(int fd, t6attr_t attr_ptr, t6mask_t *new_attrs)

     int t6last_attr(int fd, t6attr_t attr_ptr, t6mask_t *new_attrs)

DESCRIPTION
     t6peek_attr() allows a process to peek ahead at the security attributes
     of the next byte of data. fd is the descriptor of the trusted endpoint,
     attr_ptr specifies a structure in which to store those attributes the
     caller wishes to retrieve. new_attrs points to a mask that indicates
     which attributes were actually retrieved on return from t6peek_attr().

     t6last_attr() allows a process to retrieve the attributes of the last
     byte of data read from the indicated file descriptor.  Its parameters are
     identical to the t6peek_attr routine.

RETURN VALUE
     On successful completion these calls return 0, place the retrieved
     security attributes in the t6attr_t structure, and set *new_attrs to the
     mask of those attributes actually returned.  If either call encounters an
     error, -1 is returned.  Errors generated by t6peek_attr() and
     t6last_attrs() are indicated by the global variable errno.
