t6peek_attr(3N)t6peek_attr(3N)NAME
t6peek_attr, t6last_attr - examine the security attributes on the next or
previous byte of data
SYNOPSIS
cc [ flags ... ] file
#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)
DESCRIPTIONt6peek_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.
Note that the following attributes will never be returned in the argument
t6attr_t when the functions t6peek_attr and t6last_attr are called:
T6_NAT_CAVEATS, T6_ACL, T6_IL, T6_PID, T6_RESV10, T6_AUDIT_INFO,
T6_CLEARANCE.
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, the error code is returned.
ERRORS
Errors generated by t6peek_attr and t6last_attrs are indicated by the
global variable errno.
[EFAULT] If new_attrs contains a NULL pointer.
[EINVAL] Invalid Argument.
[ENOTSOCK] Socket operation on a Non-Socket not permitted.
