This, however, may not be practical in many cases and will lead * to "correct" but awkward implementations. * * boardctl() is non-standard OS interface to alleviate the problem. It * basically circumvents the normal device driver ioctl interlace and allows * the application to perform direct IOCTL-like calls to the board-specific * logic. It is especially useful for setting up board operational and * test configurations. * * Input Parameters: * cmd - Identifies the board command to be executed * arg - The argument that accompanies the command. The nature of the * argument is determined by the specific command. * * Returned Value: * On success zero (OK) is returned; -1 (ERROR) is returned on failure * with the errno variable to to indicate the nature of the failure. * ****************************************************************************/ int boardctl(unsigned int cmd, uintptr_t arg); #undef EXTERN #if defined(__cplusplus) } #endif #endif /* CONFIG_LIB_BOARDCTL */ #endif /* __INCLUDE_SYS_BOARDCTL_H */
