FWriteFmtDescription
Write formatted output to a file stream. This macro internally uses StrWriteFmtInternal to format the string and then writes it to the stream.
Parameters
| Name | Direction | Description |
|---|---|---|
stream | in | Pointer to the FILE stream to write to. |
fmtstr | in | Format string with {} placeholders. should be wrapped with variable. |
Success
Placeholders in fmtstr are replaced by the passed arguments, and the resulting formatted string is written to the specified stream.
Failure
Failure might occur during memory allocation for the temporary string or during the write operation to the stream (handled by fputs). Errors from StrWriteFmtInternal (logging messages) might also occur.
