_putstr

Hi,

Is the _putstr function in print_prv.c correct?

 

I'm using KSDK 1.3 + MQX and I am calling:

 

numChars = sprintf ("%s%s%.19s", data1, data2, data3 );

 

where data3 is a string containing 48 characters. The value returned is the length of the 3 source strings even though it has only inserted 19 of the 48 characters from data3.

When I look at _putstr it seems to set compare = true after inserting the required number of characters so the count continues to increase.

 

Should this not set continue = false to abort the loop so the returned count is the number of characters actually inserted?

Also the comments for _putstr state the default value for max_count is 0 (unlimited size), but this would results in no characters being output. Is it the comment or the code that is wrong?

 

Best regards,

Adrian.
