DLERROR(3)

NAME
dlerror - retrieve dynamic linker error messages

LIBRARY
This function is not in a library. It is included in every dynamically linked program automatically.

SYNOPSIS
#include <dlfcn.h>
char *
dlerror(void);

DESCRIPTION
The dlerror() function returns a null-terminated character string describing the last error that occurred during a call to dlopen(), dladdr(), dlinfo(), dlsym(), dlvsym(), or dlclose(). If no such error has occurred, dlerror() returns a null pointer. At each call to dlerror(), the error indication is reset. Thus in the case of two calls to dlerror(), where the second call follows the first immediately, the second call will always return a null pointer.
