Changes between Version 1 and Version 2 of Ticket #1024

v1	v2
1	1	PJSIP assumes that an {{{snprintf}}} of "%.*s" will nicely print nothing if the supplied arguments are 0 and NULL. Unfortunately some Libc library (such as uClibc) would print "(null)" instead.
2	2
3		It has been suggested that PJSIP should be changed so that it uses empty string ("") instead of NULL when the string length is zero, but this would require modifications in too many places. And ~~anyway I feel that this is not the right solution~~.

4	4
5	5	We suggest that uClibc should be fixed instead. The offending lines are in {{{libc/stdio/_vprintf.c}}}, just search for "(null)" and replace it with an empty string.
