Thread: substr and error checking

if we have a string for example "test"

and call substr(0,3) for it it will give us the string tes right?

but how does substr work when we call substr(0,10000);

it will give us the string test, but will it check until it finds a '\0' or will it check all the 10000 bytes after the first character of the string? I mean, does substr check for such errors?

substr doesn't take integer arguments. What are you talking about? substr(3): locate substring - Linux man page

I think he's referring to std::string::substr(size_t, size_t).

ok I understand it now, thanks for help
