   NAME
         getcwd - get path-name of current working directory

   SYNOPSIS
         #include <unistd.h>

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

   DESCRIPTION
         getcwd returns a pointer to the current directory path name.  The
         value of size must be at least one greater than the length of the
         path-name to be returned.

         If buf is not NULL, the pathname will be stored in the space pointed
         to by buf.

         If buf is a NULL pointer, getcwd will obtain size bytes of space
         using malloc(3C).  In this case, the pointer returned by getcwd may
         be used as the argument in a subsequent call to free.

         getcwd will fail if one or more of the following are true:

         EACCES      A parent directory cannot be read to get its name.

         EINVAL      size is less than or equal to 0.

         ERANGE      size is greater than 0 and less than the length of the
                     path name plus 1.

   EXAMPLE
         Here is a program that prints the current working directory.

               #include <unistd.h>
               #include <stdio.h>

               main()
               {
                     char *cwd;
                     if ((cwd = getcwd(NULL, 64)) == NULL)
                     {
                           perror("pwd");
                           exit(2);
                     }
                     (void)printf("%s\n", cwd);
                     return(0);
               }

   DIAGNOSTICS
         Returns NULL with errno set if size is not large enough, or if an
         error occurs in a lower-level function.
