/**
 * @brief Register a new error type, statically allocated message.
 *
 * @param msg The description of the error. This string will not be
 *        duplicated and thus the given pointer should live during
 *        usage of eina_error.
 * @return The unique number identifier for this error.
 *
 * This function stores in a list the error message described by
 * @p msg. The returned value is a unique identifier greater or equal
 * than 1. The description can be retrieve later by passing to
 * eina_error_msg_get() the returned value.
 *
 * @see eina_error_msg_register()
