Porting an input function from linux to windows

[claphahat]

void input(char *s, char *n)
{
	char *ptr;
	int c;
	
	ptr = s;
	*n = *ptr = '\0';
	do {
		c = getchar();
		switch(c) {
			case '\010':
				if(ptr > s)
					--ptr;
				break;
			case '\030':
				ptr = s;
				break;
			case '\n':
				break;
			case ' ':
				ptr = n;
				break;
			default:
				if(c >= ' ')
					*ptr++ = c;
			}
		*ptr = '\0';
	} while(c != '\n' && ptr < s + BUFFSZ);
}

this is the function i wrote to get input from the user. when i compiled it with gcc and ran it with bash it wrote the first characters to s and everything after the last space to n. when i compiled it with mingw and ran it with cmd it kept writing what was in the buffer after each space to s every time it was called. so if i typed in 3 "characters like this" in bash it would make s equal to "characters" and n equal to "this", whereas in cmd it writes "characters" to s, then "like" to s when it's next called, then "this" to s when it's next called.

does anybody know how i could rewrite this function in a way that cmd supports?

What this function is supposed to do and what does its arguments mean?

it takes the first characters before the initial space (if there is one) and places it into the first variable passed to the function, then all of the characters following the final space are placed in the second variable.
