Re: sscanf in c#

Also, theres this qualifier (3), which is the max number to read, in
the following that I would have to deal with.
sscanf(strdata[linepos], "%3x", blkout[dataframelen]);

I appreciate EVERONES help with this.

Hello,
I am the OP.
I am beginning to understand but I have the following:
sscanf(strdata[1], "%lx\n", currentAddr);

currentAddr is an unsigned long in c(which is a uint in c#) 4 bytes,
correct?

I am trying to get the hang of this, but I could use an example with
something I'm using.
I have to convert about 8 of these to dfferent formats, so its
important I can understand what I;m doing.

Thanks
Mike

| grr, that's not my point. The OP requested similar functionality to
sscanf.

Sorry, but I'm affraid we'll have to agree to disagree. I don't see how a
simple C library 'function' like sscanf compares to Regex, a 'library' and
a
complex engine on it's own, it's too heavy weight compared to sscanf.

I know you can achieve the same using RegEx, but I can do exactly that
using
some minimal code arround the individual type's Parse and TryParse
methods.
Notice, that the OP asks about sscanf, this means he has a C background,
chances are that he know little/nothing about RegEx, maybe he will prefer
to
use Parse and TryParse, the choice will be on him.

I do see where you are coming from. And yes, I will continue to disagree as
we have previously agreed to allow :) On second thought, maybe I will agree
with you about parsing out manually depending on the amount of data the OP
needs to parse. If it is a larger amount of data, and performance isn't an
issue, then I would then go with Regex for this.
