how to replace sscanf in C++,using <string>s

[Mark]

I want to replace the following line:

sscanf(mybuf,"%s=%s\n",sz1,sz2);

with something that produces the same effect, only with
dynamic storage i.e string s which is safer.

I might try this:

sscanf(mybuf.c_str(),"%s=%s\n",string1.c_str(),string2.c_str());

but unsuprisingly this causes an error at runtime since there is nothing to
stop a memory overrun happening.Additionally there is no compile time check
as sscanf uses varargs.

Can anyone recommend the quickest way of acheiving this, short of writing
my own parser.

Something similar to

string::size_type eq = mybuf.find('=');
string string1 = mybuf.substr(0, eq), string2 = mybuf.substr(eq+1);
