NAME

dlerror- get diagnostic information

SYNOPSIS

cc [ flag ... ] file ... -ldl [ library ... ]
#include <dlfcn.h>

char *dlerror(void);

DESCRIPTION

The dlerror() function returns a null-terminated character string (with no trailing newline) that describes the last error that occurred during dynamic linking processing. If no dynamic linking errors have occurred since the last invocation of dlerror(), dlerror() returns NULL. Thus, invoking dlerror() a second time, immediately following a prior invocation, will result in NULL being returned.

USAGE

The dlerror() function is one of a family of functions that give the user direct access to the dynamic linking facilities (see Linker and Libraries Guide) and are available to dynamically-linked processes only.

ATTRIBUTES

NOTES

The messages returned by dlerror() may reside in a static buffer that is overwritten on each call to dlerror(). Application code should not write to this buffer. Programs wishing to preserve an error message should make their own copies of that message.
