NAME

       getcwd() - get pathname of current working directory

SYNOPSIS

DESCRIPTION

       The  function  places the absolute pathname of the current working directory in the array pointed to by buf, and returns buf.  The value of
       size must be at least one greater than the length of the pathname to be returned.

       If buf is a NULL pointer, obtains size bytes of space using (see malloc(3C)).  In this case, the pointer returned by can  be  used  as  the
       argument  in  a subsequent call to (see malloc(3C)).  Invoking with buf as a null pointer is not recommended because this functionality may
       be removed from the HP-UX operating system in a future release.

RETURN VALUE

       Upon successful completion, returns a pointer to the current directory pathname.  Otherwise, it returns NULL with set if size is not  large
       enough, or if an error occurs in a lower-level function.

ERRORS

       fails if any of the following conditions are encountered:

	      The		  size argument is zero.

	      The		  size argument is greater than zero, but is smaller than the length of the pathname.

	      The length of the specified pathname exceeds
				  bytes, or the length of a component of the pathname exceeds bytes while is in effect.

       may fail if any of the following conditions are encountered:

	      Read or search permission is denied for a component of pathname.

	      buf		  points outside the allocated address space of the process.  may not always detect this error.

	      failed to provide   size bytes of memory.

EXAMPLES

	      #include <unistd.h>
	      #include <limits.h>

	      char *cwd;
	      char buf[PATH_MAX+1];
			...
	      if ((cwd = getcwd(buf, PATH_MAX+1)) == NULL) {
		  perror("pwd");
		  exit(1);
	      }
	      puts(cwd);
