Detailed Description

Interruptable APR-Pollset.

Typedef Documentation

apt_pollset_t

typedef typedefAPT_BEGIN_EXTERN_C struct apt_pollset_t apt_pollset_t

Wakeup builtin API of the pollset is introduced only in APR-1.4 and it is not available for APR-1.2 and APR-1.3 versions. Thus apt_pollset_t is an extension of apr_pollset_t and provides pollset wakeup capabilities the similar way as it's implemented in APR-1.4 trunkOpaque pollset declaration

Function Documentation

apt_pollset_add()

apt_bool_t apt_pollset_add	(	apt_pollset_t *	pollset,
		const apr_pollfd_t *	descriptor
	)

Add pollset descriptor to a pollset.

Parameters

pollset	the pollset to add the descriptor to
descriptor	the descriptor to add

apt_pollset_create()

apt_pollset_t* apt_pollset_create	(	apr_uint32_t	size,
		apr_pool_t *	pool
	)

Parameters

size	the maximum number of descriptors pollset can hold
pool	the pool to allocate memory from

(

apt_pollset_t *

pollset

)

apt_pollset_is_wakeup()

apt_bool_t apt_pollset_is_wakeup	(	apt_pollset_t *	pollset,
		const apr_pollfd_t *	descriptor
	)
