int vprintf ( const char * format, va_list arg );

Print formatted variable argument list to stdout

Writes to stdout the contents of the format string, expanding the format tags with the value of the argument list arg.
This function behaves exactly as printf except that the variable argument list is passed as a va_list instead of a succession of arguments, which becomes specially useful when the argument list to be passed comes itself from a variable argument list in the calling function.
vprintf does not automatically call the va_end macro.
