<h2>QlgGetcwd()--Get Current Directory (using NLS-enabled path name)</h2>

<div class="box" style="width: 80%;">
<br>
&nbsp;&nbsp;Syntax<br>
 

<pre>
 #include &lt;unistd.h&gt;

   Qlg_Path_Name_T *QlgGetcwd(Qlg_Path_Name_T <em>*buf</em>,  
   size_t <em>size</em>);

</pre>

&nbsp;&nbsp;Service Program Name: QP0LLIB2<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Default Public Authority: *USE<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Threadsafe: Conditional; see Usage Notes for <a href="getcwd.htm">getcwd()</a>.<br>
<!-- iddvc RMBR -->
<br>
</div>

<p>The <strong>QlgGetcwd()</strong> function, like the <strong>
getcwd()</strong> function, determines the absolute path name of the current
directory and returns a pointer to it. The difference is that the pointer
returned by <strong>QlgGetcwd()</strong> is a pointer to a Qlg_Path_Name_T
structure that holds the absolute path name, while <strong>getcwd()</strong>
returns a pointer to a character string or buffer that contains the
null-terminated absolute path name.</p>

<p>Limited information on the <em>buf</em> parameter and on the <em>size</em>
parameter is provided here. For more information on the parameters and for a
discussion on authorities required, return values, and related information, see
<a href="getcwd.htm">getcwd()</a>--Get Current Directory.</p>

<br>
<h3>Parameters</h3>

<dl>
<dt><strong><em>buf</em></strong></dt>

<dd>(Output) A pointer to a Qlg_Path_Name_T structure that holds the absolute
path name of the current directory. The path name is not null-terminated within
the structure. For more information on the Qlg_Path_Name_T structure, see <a
href="../apiref/pns.htm">Path name format</a>.<br>
<br>
</dd>

<dt><strong><em>size</em></strong></dt>

<dd>(Input) The number of bytes allocated for <em>buf</em>.</dd>
</dl>

<h3>Example</h3>

<p>See <a href="../apiref/aboutapis.htm#codedisclaimer">Code disclaimer information</a>
for information pertaining to code examples.</p>

<p>The following example determines the current directory:</p>

<pre>
#include &lt;unistd.h&gt;
#include &lt;stdio.h&gt;

main()
{

 #define mypath_cd "/tmp"

 const char US_const[3]= "US";
 const char Language_const[4]="ENU";
 typedef struct pnstruct
    {
     Qlg_Path_Name_T qlg_struct;
     char pn[1024];  /* This size must be large enough */
                               /* to contain the path name.     */
    };

 struct pnstruct path_cd;
 struct pnstruct path_cwd;

   /***************************************************************/
   /*   Initialize Qlg_Path_Name_T parameters                     */
   /***************************************************************/
  memset((void*)path name_cd, 0x00, sizeof(struct pnstruct));
  path_cd.qlg_struct.CCSID = 37;
  memcpy(path_cd.qlg_struct.Country_ID,US_const,2);
  memcpy(path_cd.qlg_struct.Language_ID,Language_const,3);
  path_cd.qlg_struct.Path_Type = QLG_CHAR_SINGLE;
  path_cd.qlg_struct.Path_Length = sizeof(mypath_cd)-1;
  path_cd.qlg_struct.Path_Name_Delimiter[0] = '/'
  memcpy(path_cd.pn,mypath_cd,sizeof(mypath_cd)-1);

  if (QlgChdir((Qlg_Path_Name_T *)path name_cd) != 0)
    perror("QlgChdir() error()");
  else
  {
    if (QlgGetcwd(Qlg_Path_Name_T *path_cwd,
                                  sizeof(struct pnstruct)) == NULL)
      perror("QlgGetcwd() error");
    else
      printf("Successful change to new current working directory.");
  }
}
</pre>

<p><strong>Output:</strong></p>

<pre>
Successful change to new current working directory.
