hb_FLock( <nHandle>, <nOffset>, <nBytes> [, <nType ] )
|
|
--> lSuccess
|
|
$ARGUMENTS$
|
|
<nHandle> OS file handle
|
|
|
|
set> Offset of the first byte of the region to be locked.
|
|
|
|
<nBytes> Number of bytes to be locked.
|
|
|
|
e> The type (read or write) of lock requested.
|
|
$RETURNS$
|
|
<lSuccess> .T. if the lock was obtained, else .F.
|
|
$DESCRIPTION$
|
|
This function attempts to lock a region of the file whose file handle
|
|
is <nHandle>. This is a low-level file function. To lock Harbour
|
|
data files use either the FLock() or RLock() function.
|
|
|
|
The value of <nHandle> is obtained from either a call to the FOpen()
|
|
or the FCreate() function.
|
|
|
|
<nOffset> is the offset (from the beginning of the file) to the first
|
|
of the region to be locked. (Offsets from the current position
|
|
nd of file are not currently supported.)
|
|
|
|
<nBytes> is the length of the region to be locked in bytes.
|
|
|
|
<nType> is the type of lock requested. There are two types of locks:
|
|
exclusive write locks ( <nType> = 0x0000 ) - the default, and shared
|
|
read locks ( <nType> = 0x0100 ). Additionally you can specify a
|
|
blocking version of this function (that is it won't return until
|
|
either an error has occurred or the lock has been obtained) by
|
|
adding 0x0200 to the above values.

$DESCRIPTION$
|
|
This function attempts to unlock a region of the file whose file
|

handle is <nHandle>. This is a low-level file function. To
|
|
unlock Harbour data files use the dbUnlock() function.
|
|
|

The value of <nHandle> is obtained from either a call to the FOpen()
|
|
or the FCreate() function.
|
