Detailed Description

Utility functions.

Macro Definition Documentation

a_membersof

#define a_membersof

(

arr

)

Get the number of elements in an array.

Parameters

arr

An array

Returns

Number of elements in the array

Function Documentation

a_loop_add_fd()

void a_loop_add_fd	(	int	epfd,
		int	fd,
		uint32_t	events
	)

Add a file descriptor to an epoll file descriptor.

This is a helper for epoll_ctl.

Deprecated:

[DEPR0001] This API is deprecated because it does not indicate errors while being able to fail. Please use epoll_ctl directly instead.

Parameters

epfd	epoll file descriptor
fd	The file descriptor to add
events	The events to listen for, according to epoll_ctl documentation.

a_loop_del_fd()

void a_loop_del_fd	(	int	epfd,
		int	fd
	)

Remove a file descriptor from an epoll file descriptor.

This is a helper for epoll_ctl.

Deprecated:

[DEPR0001] This API is deprecated because it does not indicate errors while being able to fail. Please use epoll_ctl directly instead.

Parameters

epfd	epoll file descriptor
fd	The file descriptor to remove

a_loop_mod_fd()

void a_loop_mod_fd	(	int	epfd,
		int	fd,
		uint32_t	events
	)

Change the events listened for on a file descriptor added to epoll.

This is a helper for epoll_ctl.

Deprecated:

[DEPR0001] This API is deprecated because it does not indicate errors while being able to fail. Please use epoll_ctl directly instead.

Parameters

epfd	epoll file descriptor
fd	The file descriptor to update
events	The events to listen for, according to epoll_ctl documentation.

a_timer_create()

int a_timer_create

(

struct itimerspec

ts

)

Create a timerfd with a given time specification.

Deprecated:

[DEPR0001] This API is deprecated due to clobbering errno and taking a structure as an argument. Please use timerfd_create and timerfd_settime directly instead.

Parameters

ts	Timer specification, as per timerfd documentation

Returns

The timer file descriptor, or negative value on error.
