.SH NAME
dlerror \- get diagnostic information
.SH SYNOPSIS
.LP
.nf
#include <dlfcn.h>

\fBchar *\fR\fBdlerror\fR(\fBvoid\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBdlerror()\fR function returns a null-terminated character string that
describes the last error that occurred during dynamic linking processing. The
returned string contains no trailing newline. If no dynamic linking errors have
occurred since the last invocation of \fBdlerror()\fR, \fBdlerror()\fR returns
\fINULL\fR. Thus, invoking  \fBdlerror()\fR a second time, immediately
following a prior invocation, results in \fINULL\fR being returned.
.SH USAGE
.sp
.LP
The \fBdlerror()\fR function is one of a family of functions that give the user
direct access to the dynamic linking facilities. These facilities are available
to dynamically-linked processes only. See \fILinker and Libraries Guide\fR.

.SH NOTES
.sp
.LP
The messages returned by  \fBdlerror()\fR can reside in a static buffer that is
overwritten on each call to \fBdlerror()\fR. Application code should not write
to this buffer. Programs wanting to preserve an error message should make their
own copies of that message.
