QNX SDP8.0Devctl and Ioctl CommandsDeveloper

This chapter describes the devctl() commands that apply to character devices. Where possible, the devctl() commands are set up so as to match the corresponding ioctl() command:

  • If there's a corresponding ioctl() command, the devctl() command is in this class:
    #define _CMD_IOCTL_TTY                  't'
      

    and the Synopsis includes the name of the ioctl() command as a comment.

  • If there isn't a corresponding ioctl() command, the devctl() command is in this class:
    #define _DCMD_CHR               0x03
