- Add man page sections '(N)' to external references, and '()' on
functions described in the same man page.
- Escape minus signs when those are expected to be used on the command
line or files.
- Mark files and variables in italic; Note headings, function names,
constants, program options and man page references in bold.
- Do not justify and hyphenate SEE ALSO section, and avoid hyphenation
on symbol names by prepending them with \%.
- Remove trailing dot from NAME section description.
- Split sections with a no-op command '.', to visually distinguish them
but to avoid introducing spurious vertical space in the formatted
output.
- Add explicit .sp commands in the SYNOPSIS section between function
prototypes, and fix space placement in function protoypes.
- Split header includes with .br (instead of the explicit or implicit
.sp) so that they are vertically contiguous.
- Add missing {} around SELINUXTYPE and POLICYTYPE variable text in
paths.
- Remove unneeded formatting commands.
- Remove spurious blank lines.

.SH "DESCRIPTION"
|
|
.BR selabel_lookup ()
|
|
performs a lookup operation on the handle
|
|
.IR hnd ,
|
|
returning the result in the memory pointed to by
|
|
.IR context ,
|
|
which must be freed by the caller using
|
|
.BR freecon (3).
|
|
The
|
|
.I key
|
|
and
|
|
.I type
|
|
parameters are the inputs to the lookup operation and are interpreted according to the specific backend that
|
|
.I handle
|
|
is open on.
|
|
|
|
.BR selabel_lookup_raw ()
|
|
behaves identically to
|
|
.BR selabel_lookup ()
|
|
but does not perform context translation.
|
|
.
|
|
.SH "RETURN VALUE"
|
|
On success, zero is returned. On error, \-1 is returned and
|
|
.I errno
|
|
is set appropriately.
|
|
.
|
|
.SH "ERRORS"
|
|
.TP
|
|
.B ENOENT
|
|
No context corresponding to the input
|
|
.I key
|
|
and
|
|
.I type
|
|
was found.
|
|
.TP
|
|
.B EINVAL
|
|
The
|
|
.I key
|
|
and/or
|
|
.I type
|
|
inputs are invalid, or the context being returned failed validation.
