Parameters

srcLen: Number of elements in the source vector.
dstLen: Number of K values to be returned, the function returns
min(K, dstLen)
elements.
dataType: Data type of the vector.
hint: Parameter to choose the optimization that is most suitable for the
srcLen+dstlen(K)
combination, supported values: ippTopKAuto/ ippTopKDirect/ ippTopKRadix.
bufSize: Size of the required work buffer.

Description

This function computes the size of the work buffer required for the

function.

Return Values

ippStsNoErr: Indicates no error.
ippStsNullPtrErr: Indicates an error when
bufSize
is NULL.
ippStsSizeErr: Indicates an error when at least one of the
srcLen
or
dstLen
values is less than, or equal to zero.
ippStsBadArgErr: Indicates an error when the
hint
value is not supported.
