vscnprintf - Format a string and place it in a buffer
int vscnprintf (char * buf, size_t size, const char * fmt,
buf The buffer to place the result into
size The size of the buffer, including the trailing null space
fmt The format string to use
args Arguments for the format string
The return value is the number of characters which have been written
into the buf not including the trailing ’\0’. If size is <= 0 the
function returns 0.
Call this function if you are already dealing with a va_list. You
probably want scnprintf instead.
