Function Documentation

rtems_capture_get_extension_index()

int rtems_capture_get_extension_index

(

void

)

Capture get extension index.

This function rturns the extension index for the capture engine.

Return values

This	method returns the extension index.

rtems_capture_get_flags()

uint32_t rtems_capture_get_flags

(

void

)

Capture get flags.

This function gets the current flag settings for the capture engine.

Return values

This	method returns the global capture flags.

rtems_capture_set_extension_index()

void rtems_capture_set_extension_index

(

int

index

)

Capture set extension index.

This function is used to set the extension index for the capture engine.

Parameters
