Any suggestions on how to highlight the already searched > string using C? The postscript language has features for doing reverse video. It is a complex and somewhat convoluted language and I am not familiar enough with it to tell you what to do. I am assuming that you are not planning on changing ggv. This leaves you with the option of running the ps file through a filter written in C (per your preference) and then displaying it. You would need to look up the postscript spec to figure out what postscript controls are needed to highlight a section of code. You might poke around for a perl module which would contain some postscript filters. I do not know of one off hand, but there have been perl modules written to do just about everything else.
