Obsurd function in MINIX???

[ekanth]

there is a file named putc.c in lib directory within src directory of MINIX source. It has a function named putc which is used by printf of stdio.h. It goes like this

#include <stdio.h>
int
(putc)(int c, FILE *stream)
{
return putc(c, stream);
}

Could anyone explain what this does. We tried a small program in C with the above form but it never ended.

the function looks to be recursive. It never stopped because it kept calling itself over and over.

We could understand that it is recursive but the thing is how will this function work? Andy Tannenbaum uses this function to print characters from the printf function of the stdio.h library. There must be something else other than just being recursive in this case atleast...
