<h4>Return Values</h4>
|
|
<p>The current drive status is returned in combination of status flags described below. FatFs refers only <tt>STA_NOINIT</tt> and <tt>STA_PROTECT</tt>.</p>
|
|
<dl class="ret">
|
|
<dt>STA_NOINIT</dt>
|
|
<dd>Indicates that the device is not initialized. This flag is set on system reset, media removal or failure of <tt>disk_initialize()</tt> function. It is cleared on <tt>disk_initialize()</tt> function succeeded. Media change that occurs asynchronously must be captured and reflect it to the status flags, or auto-mount feature will not work correctly. If the system does not support media change detect feature, application program needs to force de-initialize the file system object with <tt>f_mount()</tt> function after the media change.</dd>
|
|
<dt>STA_NODISK</dt>
|
|
<dd>Indicates that no medium in the drive. This is always cleared on fixed disk drive. Note that FatFs does not refer this flag.</dd>
|
|
<dt>STA_PROTECT</dt>
|
|
<dd>Indicates that the medium is write protected. This is always cleared on the drives without write protect feature. Not valid if no medium in the drive.</dd>
