Answer : c declaration type

>> ngx_flag_t               sendquitmsg = (s->sendquitmsg != 0);

s is a pointer to an instance of the struct that contains sendquitmsg bitfield.

s->sendquitmsg gets the value of the sendquitmsg bitfield for the s instance.

(s->sendquitmsg != 0) is true if the bitfield value is not 0 (ie. it's 1), and false if the bitfield value is 0. This result (true or false) is then assigned to the variable sendquitmsg.
