Yes i have to agree with you. My solution isn't good because
other place give "(null)" strings and pjsua not work correctly...
But when precision is 0 and string is NULL pointer what should be function
printf return? "(null)" string or "" string...I thing "(null)" is for debug
purpose...and this behavior isn't defined..
Or is this behavior some norm ?...because if not,
and it's only feature glibc then it is "hack"...don't you think?
