Question

My question ist

void function (const char **params)     
{
    const char *para;       
    para = &params[0]; //1
    para = params;     //2
    para = *&params;   //3 
}

all 3 options will be compiled by Netbeans gdb but gcc says sth like assignment from incompatible pointer type.

Why is this differnce …. got gcc 4.6.1 and what can I do in gcc to point to the value of **params with *para

Answer 1

In all three cases, the type of the right-hand side is const char **, which cannot be assigned to a const char * without a cast.

All compilers should warn you about this if you turn their warning level up high enough.

It’s not clear what you want to do; if you want to point at the beginning of the first sub-array, then this would work:

para = params[0];
