<p>The <strong>QlgOpen64()</strong> function, like the <strong>
|
||
|
|
open64()</strong> and <strong>open()</strong> functions, opens a file and
|
||
|
|
returns a number called a file descriptor. <strong>QlgOpen64()</strong> differs
|
||
|
|
from <strong>open64()</strong> in that the <strong>QlgOpen64()</strong> function
|
||
|
|
takes a pointer to a Qlg_Path_Name_T structure, while <strong>open64()</strong>
|
||
|
|
takes a pointer to a character string. <strong>QlgOpen64()</strong> differs
|
||
|
|
from <strong>open()</strong> in that it automatically opens a file with the
|
||
|
|
O_LARGEFILE flag set.</p>
|
||
|
|
|
||
|
|
<p>Limited information on the <em>path</em> parameter is provided here. For
|
||
|
|
more information on the <em>path</em> parameter and for a discussion of other
|
||
|
|
parameters, authorities required, return values, and related information, see
