MountEntries zypp::media::Mount::getEntries ( const std::string &  mtab = ""  )  [static]

Return mount entries from /etc/mtab or /etc/fstab file.

Parameters:
mtab The name of the (mounted) file system description file to read from. This file should be one /etc/mtab, /etc/fstab or /proc/mounts. Default is to try the /etc/mtab and fail back to /proc/mounts.
Returns:
A vector with mount entries or empty vector if reading or parsing of the mtab file(s) failed.
