I've profiled a program, and got this output:

	What is this _doprnt? Is there anything to do to improve it?
	Another questions... Why fprintf and putc, if I use just the first one?
Would it be better to output char by char using putc (because the output is made
of string, generated a char a time) instead of fprintf("%s")? Or would be fast way
bufferize it? Is there a faster assembler function to substitute fprintf?
	Thanks,
