ABSCheckLatent
ABS_STATUS ABSCheckLatent(
IN ABS_CONNECTION hConnection
IN void *pReserved
OUT ABS_BOOL *pboIsLatent
IN ABS_DWORD dwFlags
)
Description
Perform anti-latent check.
Note that ABSEnroll and ABSVerify perform the check implicitly
unless
it
is
disabled
with
global
parameter
ABS_PARAM_LATENT_CHECK, so you should not call this
function after ABSVerify() and ABSEnroll() after calling those
functions
(assuming
the
global
parameter
ABS_PARAM_LATENT_CHECK is turned on).
See chapter 2.1.5 for more information how the anti-latent checking
works.
Parameters
hConnection
Handle to the connection to FM.
pReserved
Reserved for future use. Set to NULL.
pboIsLatent
Pointer to ABS_BOOL, where the result of the check is stored. It is
set to ABS_TRUE, if the latest scanned finger was detected as a
latent finger; ABS_FALSE otherwise.
dwFlags
Reserved for future use. Set to zero.
Return Value
ABS_STATUS
Result code. ABS_STATUS_OK (0) means
success.
