[Coco] "C string searching question

[Bill Pierce]

<I don't suppose you have access to library functions like strlen() and
<strchr() and strstr() in that context, do you?

Yes, they are supported. I have all the "C" libraries I could find for OS9 "C"
I'm relatively "new" to "C" so this why I'm asking. I need a method of searching that is quick and easy and "C"s string routines are something I haven't delved into yet. I'm used to basic's MID$ and such and not familiar with Cs string manipulating methods. I've been doing some reading in the manuals, but the manuals seem to be a bit cryptic to say the least. The K&R manual is a little better but a lot isn't supported by MW's Coco OS9 C.

I don't suppose you have access to library functions like strlen() and
strchr() and strstr() in that context, do you?
