  11 .SH NAME

  14 .LP
  15 .nf

  22 .sp
  23 .LP
  24 The \fBgetwd()\fR function determines an absolute pathname of the current
  25 working directory of the calling process, and copies that pathname into the
  26 array pointed to by the \fIpath_name\fR argument.
  27 .sp
  28 .LP
  29 If the length of the pathname of the current working directory is greater than
  30 (\fIPATH_MAX\fR + 1) including the null byte, \fBgetwd()\fR fails and returns a
  31 null pointer.
  33 .sp
  34 .LP
  35 Upon successful completion, a pointer to the string containing the absolute
  36 pathname of the current working directory is returned.  Otherwise,
  37 \fBgetwd()\fR returns a null pointer and the contents of the array pointed to
  38 by \fIpath_name\fR are undefined.
