t6get_endpt_mask(3N)

NAME
     t6get_endpt_mask, t6set_endpt_mask, t6get_endpt_default,
     t6set_endpt_default - get or set endpoint security attribute mask, get or
     set endpoint default security attributes

SYNOPSIS
     cc [ flags ... ] file -lt6

     #include <sys/t6attrs.h>

     int t6get_endpt_mask(int fd, t6mask_t *mask)

     int t6set_endpt_mask(int fd, t6mask_t mask)

     int t6get_endpt_default(int fd, t6mask_t mask, t6attr_t attr_ptr)

     int t6set_endpt_default(int fd, t6mask_t mask, const t6attr_t attr_ptr)

DESCRIPTION
     The security extensions on the communication endpoint include a set of
     default security attributes that may be applied to outgoing data and an
     attribute mask that designates which attributes are taken from the
     endpoint's default attributes and which are taken from the process's
     effective attributes.

     By default, data written to an endpoint has associated with it the
     security attributes of the process that wrote the data.  However, a
     privileged process may change the value of the default attribute mask on
     an endpoint it had created, and the endpoint's default attributes.

     t6get_endpt_mask allows a process to obtain the current setting of the
     default attribute mask for the endpoint specified by fd.  The attribute
     mask is returned in the parameter mask.

     t6set_endpt_mask allows a process to set the bit values of the default
     attribute mask for the endpoint specified by fd to the value specified by
     mask.  A bit value of 0 indicates the attribute is taken from the
     process's effective attributes; and a bit value of 1 indicates the the
     attribute is taken from the endpoint's default attributes.

     t6get_endpt_default allows a process to get the current setting of the
     default attributes of the endpoint specified by fd.  mask indicates which
     attributes are present in the parameter attr_ptr.  To access attr_ptr,
     see t6get_attr(3N)

     t6set_endpt_default allows a process to set the default attributes of the
     endpoint specified by fd to the attributes specified by the parameter
     attr_ptr.  mask indicates which attributes are present in the parameter
     attr_ptr.  To set up attr_ptr, see t6set_attr(3N).
PRIVILEGES
     Only a process with the appropriate override privileges can change the
     endpoint's attribute mask or default attributes. To change an endpoint's
     default attribute or its mask bit, a process must have the override
     privilege corresponding to the attribute.  The override privilege
     required to specify a default attribute is implementation specific.

RETURN VALUE
     On successful completion these calls return 0.  If either call encounters
     an error, -1 is returned.
