.SH DESCRIPTION
.sp
.LP
These functions convert binary labels into hexadecimal strings that represent
the internal value.
.sp
.LP
The \fBbsltoh()\fR and \fBbsltoh_r()\fR functions convert a binary sensitivity
label into a string of the form:
.sp
.in +2
.nf
[0x\fIsensitivity_label_hexadecimal_value\fR]
.fi
.in -2
.sp

.sp
.LP
The \fBbcleartoh()\fR and \fBbcleartoh_r()\fR functions convert a binary
clearance into a string of the form:
.sp
.in +2
.nf
0x\fIclearance_hexadecimal_value\fR
.fi
.in -2
.sp

.sp
.LP
The \fBh_alloc()\fR function allocates memory for the hexadecimal value
\fItype\fR for use by \fBbsltoh_r()\fR and \fBbcleartoh_r()\fR.
.sp
.LP
Valid values for \fItype\fR are:
.sp
.ne 2
.na
\fB\fBSUN_SL_ID\fR\fR
.ad
.RS 14n
\fIlabel\fR is a binary sensitivity label.
.RE

.sp
.ne 2
.na
\fB\fBSUN_CLR_ID\fR\fR
.ad
.RS 14n
\fIlabel\fR is a binary clearance.
.RE

.sp
.LP
The \fBh_free()\fR function frees memory allocated by \fBh_alloc()\fR.
.SH RETURN VALUES
.sp
.LP
These functions return a pointer to a string that contains the result of the
translation, or \fB(char *)0\fR if the parameter is not of the required type.
.SH ATTRIBUTES

.LP
The \fBbsltoh()\fR, \fBbcleartoh()\fR, \fBbsltoh_r()\fR, \fBbcleartoh_r()\fR,
\fBh_alloc()\fR, and \fBh_free()\fR functions are Obsolete. Use the
\fBlabel_to_str\fR(3TSOL) function instead.
.sp
.LP
The \fBbsltoh()\fR and \fBbcleartoh()\fR functions share the same statically
allocated string storage. They are not MT-Safe. Subsequent calls to any of
these functions will overwrite that string with the newly translated string.
The \fBbsltoh_r()\fR and \fBbcleartoh_r()\fR functions should be used in
multithreaded applications.
