Hi,

According to the docs (QNX6.3.X), functions vsnprintf() and vsprintf()
may used in signal handlers but with the following caveat:

It's safe to call ... in a signal handler if the data isn't 
floating point.

For functions snprintf() and sprintf() there is NO such restriction.
This seems rather strange to me. 

Is the documentation really correct? And if it is, why this 
restriction?


Thanks a lot.
