GETCWD(S)



     GETCWD(S)                XENIX System V                 GETCWD(S)



     Name
          getcwd - Get the pathname of current working directory.

     Syntax
          char *getcwd (pnbuf, maxlen)
          char *pnbuf;
          int maxlen;

     Description
          getcwd returns a pointer to the current directory pathname.
          If pnbuf is a NULL pointer, getcwd will obtain maxlen bytes
          of space using malloc(S).  In this case, the pointer
          returned by getcwd may be used as the argument in a
          subsequent call to free(S).  If pnbuf is not a NULL pointer,
          then the pathname is placed in the space pointed to by pnbuf
          and pnbuf is returned.

          In all cases, the value of maxlen must be at least two
          greater than the length of the pathname to be returned.

          getcwd is implemented by using popen(S) to pipe the output
          of the pwd(C) command into the specified string space.

     Example
          char *cwd, *getcwd();
          .
          .
          .
          if ((cwd = getcwd((char *)NULL, 64)) == NULL) {
               perror(``pwd'');
               exit(1);
          }
          printf(``%s\n'', cwd);

     Errors
               [EINVAL] size is zero

               [ENOMEM] no space is available

               [ERANGE] size not large enough to hold the path name.

     Diagnostics
          Returns NULL with errno set if maxlen is not large enough.

     Notes
          maxlen must be 2 more than the true length of the pathname.
