SCardForgetReader Function
The SCardForgetReader function removes a previously introduced reader from control by
the smart card subsystem. It is removed from the smart card database, including from any
reader group that it may have been added to.
Syntax:
LONG WINAPI SCardForgetReader(
__in SCARDCONTEXT hContext,
__in LPCTSTR szReaderName
);
Parameters:
hContext [in]
Handle that identifies the resource manager context. The resource manager context
is set by a previous call to SCardEstablishContext. This parameter cannot be NULL.
szReaderName [in]
Display name of the reader to be removed from the smart card database.
Return Value:
This function returns different values depending on whether it succeeds or fails:
Success: SCARD_S_SUCCESS.
Failure: An error code. For more information, see Smart Card Return Values.
Remarks:
If the specified reader is the last member of a reader group, the reader group is
automatically removed as well.
The SCardForgetReader function is a database management function. For more information
on other database management functions, see Smart Card Database Management
Functions.
Examples:
The following example removes the display name of the specified card reader from the
system. The example assumes that lReturn is a valid variable of type LONG and that
hContext is a valid handle received from a previous call to the SCardEstablishContext
function.
lReturn = SCardForgetReader(hContext,
TEXT("MyReader"));
if ( SCARD_S_SUCCESS != lReturn )
printf("Failed SCardForgetReader\n");
