Parameters

srcLen

Number of patterns in the source array.

patternLen

Number of elements in the templates array.

patternSize

The size of a pattern, in bytes.

hint

Option to run specially optimized code branch, supported values:

ippPatternMatchAuto	The function selects optimization automatically.
ippPatternMatchDirect	The function uses direct method, no additional memory is required.
ippPatternMatchTable	The function uses conversion data for internal representation and requires the memory buffer. Helps to achieve better performance for a big set of input data.

bufSize

Size of the required buffer.
