# OS_GetPrintBlockingMode

## Syntax

  `#include <nitro/os.h>`
  `BOOL OS_GetPrintBlockingMode( void );`

## Arguments

None.

## Return Values

Returns the current setting values.

If `TRUE`, blocking mode; if `FALSE`, non-blocking mode.

## Description

Gets the blocking mode setting for IS-TWL-DEBUGGER or IS-NITRO-DEBUGGER debugger output.

See `OS_SetPrintBlockingMode`, the function that sets the blocking mode, for a description of the blocking mode.

This function is used for debugging. This function always returns `FALSE` with the FINALROM library.

The blocking mode switching feature is sometimes not implemented depending on the version of IS-TWL-DEBUGGER and IS-NITRO-DEBUGGER. Check the debugging software update history. You can call this function even when the feature is unsupported. If the feature is unsupported, `OS_GetPrintBlockingMode` always returns `FALSE`.

If no settings have been configured, the initial value depends on the implementation of the debugger software.
