NAME

bltype, setbltype– compare and set the type of binary label

SYNOPSIS

cc [flag…] file… -ltsol [library…]


#include <tsol/label.h>

int bltype(const void *label, const unsigned char type);
void setbltype(void *label, const unsigned char type);

DESCRIPTION

These functions compare and set the type of binary labels.

bltype() examines label to determine if it is of the specified type type.

setbltype() sets the type of label to the specified type type.

type may be one of:

SUN_SL_ID

label is a defined binary sensitivity label.

SUN_SL_UN

label is an undefined binary sensitivity label.

SUN_CLR_ID

label is a defined binary clearance.

SUN_CLR_UN

label is an undefined binary clearance.

SUN_CMW_ID

label is a binary CMW label whose label portions may or may not be defined. (bltype() only.)

RETURN VALUES

bltype() returns non-zero if label is of type type, otherwise zero is returned.

WARNINGS

1. bltype(&cmw_label, SUN_CMW_ID) checks the existence of a binary CMW label structure and not the portions of the structure that contain defined labels.

2. When attempting to determine the type of a label, rather than to verify that a specific label type is present, check SUN_CMW_ID first.

3. setbltype() makes no checks on the structure it is setting or the type value.
