char *dlerror(void);
Link with -ldl.
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.
dlerror() is present in glibc 2.0 and later.
