\fR
.SH "DESCRIPTION"
.PP
\fBlwres_conf_init()\fR
creates an empty
\fBlwres_conf_t\fR
structure for lightweight resolver context
\fIctx\fR.
.PP
\fBlwres_conf_clear()\fR
frees up all the internal memory used by
that
\fBlwres_conf_t\fR
structure in resolver context
\fIctx\fR.
.PP
\fBlwres_conf_parse()\fR
opens the file
\fIfilename\fR
and parses it to initialise the resolver context
\fIctx\fR's
\fBlwres_conf_t\fR
structure.
.PP
\fBlwres_conf_print()\fR
prints the
\fBlwres_conf_t\fR
structure for resolver context
\fIctx\fR
to the
\fBFILE\fR
\fIfp\fR.
.SH "RETURN VALUES"
.PP
\fBlwres_conf_parse()\fR
returns
LWRES_R_SUCCESS
if it successfully read and parsed
\fIfilename\fR.
It returns
LWRES_R_FAILURE
if
\fIfilename\fR
could not be opened or contained incorrect
resolver statements.
.PP
\fBlwres_conf_print()\fR
returns
LWRES_R_SUCCESS
unless an error occurred when converting the network addresses to a
numeric host address string.
If this happens, the function returns
LWRES_R_FAILURE.
