dlerror() -- return last dynamic linking error

SYNOPSIS

#include <dlfcn.h>

char *dlerror(void);

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, results in NULL being returned.

PARAMETERS

None.

RETURN VALUES

dlerror() returns a null-terminated character string describing the last error that occurred during a dlopen(), dlsym(), or dlclose(). If no such error has occurred, then dlerror returns NULL.
