CC65 compiler error help

hi,

Using CC65 compiler..

code:

while(1) {


if ( url_ready_flag == 0 ) {
*(url_host) = 0;
url_ready(url_host, url_page);
if (url_host != "") {
resolv_query(url_host);
}
}


I'm NOT a C language programmer, but I'm learning because the project
interests me (I'm doing the assembly language)

what is wrong with the above code?

if (url_ready_flag == 0) {

line generates errors:

) expected
expression expected
statement has no effect
; expected

anyone know whats going on ?
