Method and system for inserting floating code hooks into multiple versions of code

A system for inserting a floating code hook at a proper position within a program's code, the system comprising:

• means for estimating an insertion point for a code hook in a computer program loaded in a computer's memory;
• means for determining whether expected code is located at the estimated insertion point;
• and
• means for, if the expected code is located at the estimated insertion point, inserting the code hook into the program code at the insertion point, and, if the expected code is not located at the estimated insertion point, moving the estimated insertion point a predetermined number of bytes from the estimated insertion point to a new estimated insertion point.

A computer program product for use in a computer system comprising:

• computer usable medium having computer readable program code means embodied therein for estimating an insertion point for a code hook in a computer program loaded in a computer's memory;
• computer readable program code means for determining whether expected code is located at the estimated insertion point;
• and
• computer readable program code means for, if the expected code is located at the estimated insertion point, inserting the code hook into the program code at the insertion point, and, if the expected code is not located at the estimated insertion point, moving the estimated insertion point a predetermined number of bytes from the estimated insertion point to a new estimated insertion point.
