() returns the earliest error code from the thread's error queue and removes the entry. This function can be called repeatedly until there are no more error codes to return.

() returns the earliest error code from the thread's error queue without modifying it.

() returns the latest error code from the thread's error queue without modifying it.

See ERR_GET_LIB(3) for obtaining information about the location and reason for the error, and ERR_error_string(3) for human-readable error messages.

(), (), and () are the same as the above, but they additionally store the file name and line number where the error occurred in *file and *line, unless these are NULL.

(), (), and () store additional data and flags associated with the error code in *data and *flags, unless these are NULL. *data contains a string if *flags&ERR_TXT_STRING is true.

An application free the *data pointer (or any other pointers returned by these functions) with free(3) as freeing is handled automatically by the error library.

The error code, or 0 if there is no error in the queue.
