  10 .TH GETWD 3C "Jul 24, 2002"
  11 .SH NAME
  12 getwd \- get current working directory pathname
  13 .SH SYNOPSIS
  14 .LP
  15 .nf
  16 #include <unistd.h>
  17 
  18 \fBchar *\fR\fBgetwd\fR(\fBchar *\fR\fIpath_name\fR);
  19 .fi
  20 
  21 .SH DESCRIPTION
  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.
  32 .SH RETURN VALUES
  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.
  39 .SH ERRORS
  40 .sp
  41 .LP
  42 No errors are defined.
  43 .SH USAGE
  44 .sp
  45 .LP
  46 For portability to implementations conforming to versions of the X/Open
  47 Portability Guide prior to SUS, \fBgetcwd\fR(3C) is preferred over this
  48 function.
