[En-Nut-Discussion] How to get free memory space on SD Memory card

[Eric Haver]

Hi Helmut,

I am using Nut 4.4.0

>From here it looks like:
*/*!
 * \brief Counts the number of free clusters in a volume.
 *
 * \param dev Specifies the file system device.
 *
 * \return The number of free clusters.
 */
static u_long PhatCountFreeClusters(NUTDEVICE * dev)
*
will answer your question.

Find it in nut\fs\phatvol.c


Gruß,

*Eric
