<p>The <strong>getcwd()</strong> function determines the absolute path name of
|
||
|
|
the current directory and stores it in <em>buf</em>. The components of the
|
||
|
|
returned path name are not symbolic links.</p>
|
||
|
|
|
||
|
|
<p>The access time of each directory in the absolute path name of the current
|
||
|
|
directory (excluding the current directory itself) is updated.</p>
|
||
|
|
|
||
|
|
<p>If <em>buf</em> is a NULL pointer, <strong>getcwd()</strong> returns a NULL
|
||
|
|
pointer and the [EINVAL] error.</p>

<h3>Parameters</h3>

|
|
||
|
|
<dl>
|
||
|
|
<dt><strong><em>buf</em></strong></dt>
|
||
|
|
|
||
|
|
<dd>(Output) A pointer to a buffer that will be used to hold the absolute path
|
||
|
|
name of the current directory. The buffer must be large enough to contain the
|
||
|
|
full pathname including the terminating NULL character. The current directory
|
||
|
|
is returned in the CCSID (coded character set identifier) currently in effect
|
||
|
|
for the job. If the CCSID of the job is 65535, this parameter is assumed to be
|
||
|
|
represented in the default CCSID of the job.

|
|
||
|

<p>See <a href="getcwdu.htm">QlgGetcwd()--Get Current Directory</a> for a
