Declaration

function IndexQWord(

  const buf;

  len: SizeInt;

  b: QWord

):SizeInt;

Description

IndexQWord checks the first len qwords starting at Buf, and returns the position (zero-based) of b. If b does not appear in the first len qwords, then -1 is returned.

Note that the search is done on QWord boundaries, but that the address of buf need not be on a QWord boundary.

Errors

No check is done to see whether the indicated memory range is valid. If it is not, a run-error or exception may be triggered.
