int fifo_open | ( | pipe_control_t ** | pipep, |
rtems_libio_t * | iop | ||
) |
File system open. Interface to file system open.
*pipep points to pipe control structure. If called with *pipep = NULL, fifo_open will try allocating and initializing a control structure. If the call succeeds, *pipep will be set to address of new control structure.
int pipe_ioctl | ( | pipe_control_t * | pipe, |
ioctl_command_t | cmd, | ||
void * | buffer, | ||
rtems_libio_t * | iop | ||

File system Input/Output control.
Interface to file system ioctl.
ssize_t pipe_read | ( | pipe_control_t * | pipe, |

Interface to file system read.
void pipe_release | ( | pipe_control_t ** | pipep, |
rtems_libio_t * | iop | ||
) |
Release a pipe.
Interface to file system close.
*pipep points to pipe control structure. When the last user releases pipe, it will be set to NULL.

const void * | buffer, | ||
