libio: Update number of written bytes in dprintf implementation
|
||||
|
||||
The __printf_buffer_flush_dprintf function needs to record that
|
||||
the buffer has been written before reusing it. Without this
|
||||
accounting, dprintf always returns zero.
|
||||
|
||||
Fixes commit 8ece45e4f586abd212d1c02d74d38ef681a45600
|
||||
("libio: Convert __vdprintf_internal to buffers").
