DebugPrintf
int DebugPrintf (const char formatString[], ...);
Purpose
Similar to the ANSI C printf function, but writes output to the LabWindows/CVI Debug Output Window, when LabWindows/CVI is debugging the program. If the program is not being debugged, no output occurs.
(Linux) This function is not supported.
If another development environment is debugging the program, the output can appear in debugging output window of that development environments.
This function does not automatically append a newline character to the output.
Parameters
| Input | ||
| Name | Type | Description |
| formatString | const char [] | The format string that specifies how subsequent arguments are converted
for output. The format string format is identical to the format supported by the ANSI C printf function. Refer to the documentation for the ANSI C printf function for information about the format. If the format requires more arguments than the number of arguments passed to this function, the behavior is undefined. If the format is exhausted while arguments remain, the excess arguments are evaluated but are otherwise ignored. |
| source_s | ... | Specifies one or more arguments that are to be converted and written to the
debug output window. You must separate multiple arguments by commas. |
Return Value
| Name | Type | Description |
| CharactersWritten | int | The number of characters transmitted, or a negative value if an output error occurred. |
