+ * to strings.
* @param argv
- * The argv argument that was given to the main() function.
+ * An array of strings. The contents of the array, as well as the strings
+ * which are pointed to by the array, may be modified by this function.
* @return
* - On success, the number of parsed arguments, which is greater or

- * not be accessed by the application.
- * - On failure, a negative error value.
+ * all arguments argv[x] with x < ret may have been modified by this
+ * function call and should not be further interpreted by the
+ * application. The EAL does not take any ownership of the memory used
+ * for either the argv array, or its members.
+ * - On failure, -1 and rte_errno is set to a value indicating the cause
+ * for failure. In some instances, the application will need to be
+ * restarted as part of clearing the issue.
+ *
+ * Error codes returned via rte_errno:
+ * EACCES indicates a permissions issue.
+ *
+ * EAGAIN indicates either a bus or system resource was not available,
+ * setup may be attempted again.
+ *
+ * EALREADY indicates that the rte_eal_init function has already been
+ * called, and cannot be called again.
+ *
+ * EFAULT indicates the tailq configuration name was not found in
+ * memory configuration.
+ *
+ * EINVAL indicates invalid parameters were passed as argv/argc.
+ *
+ * ENOMEM indicates failure likely caused by an out-of-memory condition.
+ *
+ * ENODEV indicates memory setup issues.
+ *
+ * ENOTSUP indicates that the EAL cannot initialize on this system.
+ *
+ * EPROTO indicates that the PCI bus is either not present, or is not
+ * readable by the eal.
+ *
+ * ENOEXEC indicates that a service core failed to launch successfully.
