ozo, why do you insist on posting perfectly good answers as comments?<br />

Well, I actually seem to have made a typo of scanf for sscanf,<br />
But I figure it's up to the questioner to determine what's a perfectly good answer,<br />
and I'd rather err on the safe side than have a reputation of posting<br />
perfectly poor comments as answers.<br />
And in this case, I didn't think I could give a complete answer,<br />
not knowing what zackeel meant by «equivalent strings» for &quot;1cf3bei4&quot;<br />

Hi,<br />
<br />
I am in need of a function to transform hex strings (for ex: &quot;1cf3bei4&quot;) to their<br />
equivalent strings or unsigned long int.<br />
<br />
Thank you.

Hi,

I am in need of a function to transform hex strings (for ex: "1cf3bei4") to their
equivalent strings or unsigned long int.

Thank you.

I need a hex2str or hex2int function.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
