converting char array to integer

[those who know me have no need of my name]

in comp.lang.c i read:

by the way..

char str[5] = "5678";
int intvar = (int *)str;

doesnt work either.

naturally. are you learning c as a hobby? if you really are implementing
something serious in c please learn the language first, or post the name of
the device(s) so we can avoid being near them.

Except that it will lead to overflow when the other solution won't.

Mapping char array to integer is not portable across architectures.
You need to consider byte ordering issues on different platforms.
