Subject: printf() and _write() in newlib-nano
Date: Wed, 19 Apr 2017 08:55:00 -0000 [thread overview]
Message-ID: <02d116cb-f9a6-8f0c-8ab2-8dda8cec8f37@powersoft.it> (raw)
I use newlib-nano in an embedded project.
I have implemented my version of _write() to make printf() output chars
to UART.
I wonder if a single call of printf() results in a single call of
_write(), or, otherwise _write() can be called more than once by printf().
best regards
Max
