Bug in MQX 3.8 printf ignoring width specifier

RoyAtRce — Wed, 30 May 2012 05:00:06 GMT

The printf implementation in MQX 3.8 appears to be ignoring the width specifier for strings.

I expect

printf("%3.3", "ABCD")

to output:

ABC

but I actually get:

ABCD

Its actually the precision not the width it is mishandling.

Hello RoyAtRce,

your printf contains width (specifies minimum characters) and also a precision specifier (maximum characters). This applies to strings.

I tested it and it really ignores the precision specifier.

Thanks for your feedback. We are going to fix this.
