t6get_attr(3N)

NAME
     t6get_attr, t6set_attr - Get or set security attributes

SYNOPSIS
     cc [ flags ... ] file -lt6

     #include <tsix/t6attrs.h>

     void *t6get_attr(t6attr_id_t attr_type, const t6attr_t t6ctl)

     int t6set_attr(t6attr_id_t attr_type, const void *attr_buf, t6attr_t
     t6ctl)

DESCRIPTION
     t6get_attr() takes a control structure, t6ctl, and attribute type,
     attr_type, and returns a pointer to the requested attribute value (type)
     from the opaque control structure t6ctl. attr_type contains a number
     defined in <sys/t6attrs.h> that specifies what type of attribute that the
     caller is interested in getting.  Only one type can be specified per
     call.

     Returned value by t6get_attr() should be type cast to the standard type
     that represents the type indicated by attr_type.

     t6set_attr() replaces the requested attribute value (type) in t6ctl with
     the value pointed to by attr_buf.  Type of the attribute is specified in
     attr_type as one of the numbers defined in <sys/t6attrs.h>.

RETURN VALUE
     On successful completion, t6get_attr() returns a pointer to the
     appropriate value if it exists in the attribute structure, otherwise it
     returns NULL.  t6set_attr() returns 0 if the attribute structure can
     contain the requested attribute, otherwise it returns -1 and does not
     change the attribute structure.
