NAME

ScanStackToken: Find default stack of segment list (V47)

SYNOPSIS

stack = ScanStackToken(segment, defaultstack)
D0 D1 D2

LONG ScanStackToken(BPTR segment, LONG defaultstack)

FUNCTION

This function scans a segment list for the magic stack token, i.e. "$STACK:<size>" and adjusts the default stack size passed in accordingly. The return value is the maximum of the second argument, and all stack tokens found in the segment list.

INPUTS

segment: a segment list, as returned by LoadSeg()
defaultstack: default stack size in bytes

RESULT

The stack size recorded in the segment list, computed as the maximum of the passed in size and all stack tokens found in the segment list.

NOTES

This function uses a variant of the Knuth-Morris-Pratt fast string search algorithm to keep the complexity time as low as possible.
