GETCWD(3C)                           SysV                           GETCWD(3C)



NAME
     getcwd - get pathname of current working directory

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

DESCRIPTION
     getcwd returns a pointer to the current directory pathname.  The value of
     size must be at least two greater than the length of the pathname to be
     returned.

     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.

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

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