DiskSpace()
$CATEGORY$

$ONELINER$
Get the amount of space available on a disk
$SYNTAX$
DiskSpace( [<nDrive>] ) --> nDiskbytes
$ARGUMENTS$
<nDrive> The number of the drive you are requesting info on where 1 = A,
2 = B, etc. For 0 or no parameter, DiskSpace will operate on the current
drive. The default is 0
$RETURNS$
<nDiskBytes> The number of bytes on the requested disk that match the
requested type.
$DESCRIPTION$
By default, this function will return the number of bytes of
free space on the current drive that is available to the user
requesting the information.
If information is requested on a disk that is not available, a runtime
error 2018 will be raised.

$CATEGORY$
API

FileSys
$ONELINER$
Get the amount of space available on a disk
$SYNTAX$
hb_DiskSpace( [<cDrive>] [, <nType>] ) --> nDiskbytes
$ARGUMENTS$
<cDrive> The drive letter you are requesting info on. The default
is A:
<nType> The type of space being requested. The default is HB_DISK_AVAIL.
$RETURNS$
<nDiskBytes> The number of bytes on the requested disk that match the
requested type.
$DESCRIPTION$
By default, this function will return the number of bytes of
free space on the current drive that is available to the user
requesting the information.
There are 4 types of information available:
HB_FS_AVAIL The amount of space available to the user making the
request. This value could be less than HB_FS_FREE if
disk quotas are supported by the O/S in use at runtime,
and disk quotas are in effect. Otherwise, the value
will be equal to that returned for HB_FS_FREE.
HB_FS_FREE The actual amount of free diskspace on the drive.
HB_FS_USED The number of bytes in use on the disk.
HB_FS_TOTAL The total amount of space allocated for the user if
disk quotas are in effect, otherwise, the actual size
of the drive.
If information is requested on a disk that is not available, a runtime
error 2018 will be raised.
$EXAMPLES$
#include "fileio.ch"
? "You can use : " + hb_ntos( hb_DiskSpace() ) + " bytes " +;
"Out of a total of " + hb_ntos( hb_DiskSpace( "C:", HB_FS_TOTAL ) )
