Vfprintf(3) with extended firestring types
#include <firestring.h>
-lfirestring
long firestring_vfprintf(FILE * stream, const char * const format, va_list ap)
firestring_vfprintf() behaves exactly like firestring_snprintf(3) except that it writes to the STDIO stream specified by stream and accepts a stdarg object instead of a list of arguments.
Returns the number of bytes written.
