Hex Mnemonic Description
0x2003 E_BADVOL Inconsistent data on volume; volume
corrupted.
0x2006 E_MNTFULL Attempted to mount too many volumes.
0x2007 E_VALIEN Wrong volume format.
0x2008 E_MNTED Volume is already mounted.
0x2021 E_ILLDEV Illegal device (exceeded maximum).
0x2024 E_FMODE Illegal synchronization mode.
0x2025 E_IDN Illegal device name.
0x2029 E_NMSVOL Cannot mount MS-DOS volume.
0x2051 E_MAXLOOP Symbolic links nested too deeply.
1. pcmount_vol() proceeds as if the designated pSOS+ device is mountable. A
device is mountable if it has been initialized by pcinit_vol() or by the
MS-DOS FORMAT command.
2. The number of volumes that can be mounted simultaneously in the system
cannot exceed the pHILE+ Configuration Table parameter fc_nmount (from
sys_conf.h).
3. The pHILE+ file system manager does not attempt verification or any other way
of determining volume ownership. Any task can perform a pcmount_vol(). A
mounted device does not retain a record of the task that mounted it. Therefore,
a volume is not automatically unmounted when the task that mounted it is
deleted. This and any other security measures, if desired, should be supported
by the user’s own layer of software.
4. For an application to mount an MS-DOS volume, the mount flag FC_MSDOS in
sys_conf.h must be set.
