VirtualBox

source: vbox/trunk/src/VBox/Runtime/RTErrConvertFromErrno.cpp@ 1532

Last change on this file since 1532 was 1532, checked in by vboxsync, 18 years ago

Handle EFBIG on Linux correctly (and try to detect the same situation on
Windows). Provide separate runtime error message, because disk full
doesn't describe the problem (file size limit exceeded). Happens mostly
if people store VDIs on FAT32 partitions.
