Macro Definition Documentation

WEXITSTATUS

#define WEXITSTATUS

(

stat_val

)

Value:

((unsigned)(stat_val) >> 8)

WIFEXITED

#define WIFEXITED

(

stat_val

)

Value:

(((stat_val) & 255) == 0)

Function Documentation

asp_getsession()

ASP asp_getsession	(	ASP	asp,
		server_child_t *	server_children,
		const int	tickleval )

This call handles open, tickle, and getstatus requests.

Note

On a successful open, it forks a child process.

Returns

an ASP to the child and parent and NULL if there is an error.

asp_kill()

void asp_kill

(

int

sig

)

kill children

asp_stop_tickle()

void asp_stop_tickle

(

void

)

set_asp_ac()

void set_asp_ac ( int sid, struct asp_child * tmp )

static

tickle_handler()

void tickle_handler ( int sig )

static

send tickles and check tickle status of connections

thoughts on using a hashed list:

• + child_cleanup, finding slots
• - tickle_handler, freeing, tickles

if setup for a large number of connections:

• + space: if actual connections < potential
• - space: actual connections ~ potential
