GetBoxMappingHRCRESULT
2.0
Returns the box indices for a range of symbols.
int GetBoxMappingHRCRESULT( HRCRESULT hrcresult, UINT iSyv, UINT cSyv, UINT FAR * rgi )
Parameters
hrcresult
Handle of a results object.
iSyv
Index of the first symbol of interest in the results object.
cSyv
The number of symbols following
iSyv for which box indices are required. Note that the array
rgi must be large enough to accommodate this many items of size UINT. A value of
0 is allowed, in which case the function simply returns 0.
rgi
Address of an index array. The array must be large enough to store
cSyv indices. This address cannot be NULL.
Return Value
Returns the number of indices actually retrieved, if successful. This can be
less than the space allocated in
rgi if
iSyv indexes an element near the end of the results array, and is 0 if
iSyv indexes a nonexistent element; otherwise, returns one of the following
negative values:
Constant
 Description

HRCR_ERROR
 Invalid parameter or other error.

HRCR_MEMERR
 Insufficient memory.

HRCR_UNSUPPORTED
 The recognizer does not support this function.

Comments
GetBoxMappingHRCRESULT is typically used with boxed input established by
SetGuideHRC. If no guide structure has been set, the recognizer will return HRCR_ERROR.
It is possible to allocate a small buffer in
rgi and call
GetBoxMappingHRCRESULT repeatedly, incrementing the index
iSyv each time by the number of indices returned in the previous call until
GetBoxMappingHRCRESULT returns 0.
