error: invalid lvalue in assignment

[yyhkitty]

Hi,

I keep getting two invalid lvalue in assignment errors. here's what my code looks like:

pthread_t msg_receive(char *sbuffer, int *maxlen) {
    // get the values for sbuffer and maxlen
 
    strcpy(sbuffer, current->message);
    &maxlen = current->messagelen;      // invalid lvalue here
}
 

current is a struct ptr with these attributes:

current {
    char *message;
    int messagelen;
    char *replymsg;
    int replylen;
}

the other place i'm getting the lvalue error is basically the same. me trying to deference an int to assign it a value from a struct.

I'd really appreciate if someone can tell me what i've done wrong.

thanks.

&maxlen

& is not the de-reference operator, it's the address-of operator. You're using it to find the address of the pointer to an integer. You should be using *, like so:

*maxlen
