char *dlerror(void);

The dlerror() function returns a human-readable, null-terminated string describing the most recent error that occurred from a call to one of the functions in the dlopen API since the last call to dlerror(). The returned string does not include a trailing newline.

dlerror() returns NULL if no errors have occurred since initialization or since it was last called.
