# OS_TPrintf

## C Specification

  `#include <nitro/os.h>
  void OS_TPrintf( const char *fmt, ...`

## Arguments

fmt | Character string output format (character string format)
... | Variable number of arguments

## Return Values

None.

## Description

Displays the character string. Internally, this function calls `OS_VSNPrintf()`. Therefore the useable character string format (character string output format) is more restricted than it would be with `OS_Printf()`. However, you can save on the code and stack overhead by using this function instead of `OS_Printf()`.

This function is compiled with weak symbols. Therefore you can overwrite them with your own function definitions.

This function is used for debugging. It will not be generated in the final ROM version (`FINALROM`).
