char *getcwd(char *buf, int size);

Parameters for this facility are:

buf	char	A buffer to hold the pathname of the current working directory
size	int	The size of the buffer

The function getcwd() takes two arguments. One is a buffer large enough to store the full directory pathname, the other argument is the size of that buffer.

If successful, getcwd() returns a pointer to the buffer. If unsuccessful, getcwd() returns NULL and sets errno.
