The dynamic thread API changed, and so does the documentation.

 /* struct CRYPTO_dynlock_value needs to be defined by the user */

 typedef struct CRYPTO_dynlock_value CRYPTO_dynlock;

 struct CRYPTO_dynlock_value;

 void CRYPTO_set_dynlock_create_callback(CRYPTO_dynlock *(*dyn_create_function)

	(char *file, int line));

 void CRYPTO_set_dynlock_create_callback(struct CRYPTO_dynlock_value *

	(*dyn_create_function)(char *file, int line));

 void CRYPTO_set_dynlock_lock_callback(void (*dyn_lock_function)

	(int mode, CRYPTO_dynlock *l, const char *file, int line));

	(int mode, struct CRYPTO_dynlock_value *l,

	const char *file, int line));

 void CRYPTO_set_dynlock_destroy_callback(void (*dyn_destroy_function)

	(CRYPTO_dynlock *l, const char *file, int line));

	(struct CRYPTO_dynlock_value *l, const char *file, int line));

 int CRYPTO_get_new_dynlockid(void);

   // no thread support

 #endif

Also, dynamic locks are currently not used internally by OpenSSL, but

may do so in the future.
