.SH DESCRIPTION
.sp
.LP
The \fBgetlabel()\fR function obtains the sensitivity label of the file that is named by \fIpath\fR. Discretionary read, write or execute permission to the final component of \fIpath\fR is not required, but all directories in the path prefix of \fIpath\fR must be searchable.
.sp
.LP
The \fBfgetlabel()\fR function obtains the label of an open file that is referred to by the argument descriptor, such as would be obtained by an \fBopen\fR(2) call.
.sp
.LP
The \fIlabel_p\fR argument is a pointer to an opaque label structure. The caller must allocate space for \fIlabel_p\fR by using \fBm_label_alloc\fR(3TSOL).
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBgetlabel()\fR and \fBfgetlabel()\fR return 0. Otherwise they return \(mi1 and set \fBerrno\fR to indicate the error.
.SH ERRORS
.sp
.LP
The \fBgetlabel()\fR function will fail if:
.sp
.ne 2

\fB\fBEACCES\fR\fR

Search permission is denied for a component of the path prefix of \fIpath\fR. To override this restriction, the calling process can assert the \fBPRIV_FILE_DAC_SEARCH\fR privilege.
