NAME
       getcwd - get current working directory pathname

SYNOPSIS
       #include <unistd.h>

       char *getcwd(char *pathname, size_t len)

DESCRIPTION
       Getcwd  copies the absolute pathname of the current working directory to pathname and returns a pointer to the result.  Pathname is a char-
       acter array of length len.

DIAGNOSTICS
       Getcwd returns a null pointer and sets errno if an error occurs.  The error will reflect the system call errors that may occur if the  path
       to  the	current  directory  is searched upwards to the root directory.	The error ERANGE is returned if the result does not fit within len
       bytes.
