 .SH DESCRIPTION
-.LP
 The \fBnetdir\fR functions provide a generic interface for name-to-address
 mapping that will work with all transport protocols. This interface provides a
 generic way for programs to convert transport specific addresses into common
 structures and back again. The \fBnetconfig\fR structure, described on the
 \fBnetconfig\fR(4) manual page, identifies the transport.

 The \fBnetdir_options()\fR function is used to do all transport-specific setups
 and option management. \fIfildes\fR is the associated file descriptor.
 \fIoption\fR, \fIfildes\fR, and \fIpointer_to_args\fR are passed to the
 \fBnetdir_options()\fR function for the transport specified in \fIconfig\fR.
 Currently four values are defined for \fIoption\fR:

 The \fBnetdir_sperror()\fR function returns a string with an error message that
 states the cause of a name-to-address mapping failure.
 
 .SH RETURN VALUES
-.LP
 The \fBnetdir_sperror()\fR function returns a pointer to a buffer which
 contains the error message string. The buffer is overwritten on each call. In
 multithreaded applications, this buffer is implemented as thread-specific
 data.

 The \fBnetdir_getbyname()\fR, \fBnetdir_getbyaddr()\fR, and \fBnetdir_options()\fR
 functions return \fB0\fR on success and a non-zero value on failure.
