<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
|
||
|
