C++ string to char conversion -

i have function requires parameter of type 'unsigned char'.

if use:

unsigned char x[8] = "a\0ab-cd";

and pass 'x' parameter function call, desired result.

however, inputs rwcstrings, , not char type variable.

in case, have :

rwcstring a1 = "a"; rwcstring b1 = "ab-cd";

i try concatenate using :

rwcstring final = a1 + "\0" + b1;

and try using conversion inside function call (unsigned char*) final.data();

however, produces different result called function.

what doing wrong here ?

when doing a1 + "\0" operation, sourcepro evaluates "\0" string length = 0, returning a1.

the documentation += operator notes operator doesn't support strings embedded nulls.
