|
|
* @brief Formatted output conversion
|
|
*
|
|
* These functions write the output under the control of a format
|
|
* string that specifies how subsequent arguments (or arguments
|
|
* accessed via the variable-length argument facilities of stdarg(2))
|
|
* are converted for output.
|
|
*
|
|
* They do not write more than \a size bytes, including the trailing
|
|
* \c '\0'.
|
|
*
|
|
* These functions return the number of characters printed (not
|
|
* including the trailing \c `\0' used to end output to strings). They
|
|
* return -1 if the output was truncated due to the @a size limit.
