Function Documentation

event_eventfd_create()

int event_eventfd_create

(

void

)

Creates an eventfd with semaphore semantics

Returns

the eventfd

event_eventfd_create_simple()

int event_eventfd_create_simple

(

void

)

Creates an eventfd

Returns

the eventfd

event_eventfd_read()

bool event_eventfd_read

(

int

fd

)

Reads from an eventfd

Parameters

fd	read from this fd

Returns

true on success, else false

event_eventfd_read_number()

eventfd_t event_eventfd_read_number

(

int

fd

)

Reads from an eventfd and returns the number read. Sets errno to 0 on success, else sets errno to the error code.

Parameters

fd	read from this fd

Returns

the number read from the eventfd

event_eventfd_write()

bool event_eventfd_write

(

int

fd

)

Increments the eventfd by one

Parameters

fd	fd to write

Returns

true on success, else false

event_fd_close()

void event_fd_close

(

int

fd

)

Closes the fd

Parameters

fd	fd to close

event_pfd_add_fd()

bool event_pfd_add_fd	(	struct mympd_pfds *	pfds,
		int	fd,
		enum pfd_type	type,
		struct t_partition_state *	partition_state )

Adds an fd to poll

Parameters

pfds	struct to add the fd
fd	fd to add
type	fd type to add
partition_state	pointer to partition_state or NULL

Returns

true on success, else false

event_pfd_init()

void event_pfd_init

(

struct mympd_pfds *

pfds

)

Initializes the mympd_pfds struct to zero

Parameters

pfds	struct to initialize

lookup_pfd_revents()

const char * lookup_pfd_revents

(

short

revent

)

Lookups the name for poll revents

Parameters

revent

poll return event

Returns

name as string

lookup_pfd_type()

const char * lookup_pfd_type

(

enum pfd_type

type

)

Lookups the name for a pfd_type

Parameters

type

pfd_type

Returns

name as string
