		void()(void , void *)	release
	)

inherited

Set user data with copy and release functions.

Parameters

data	Pointer to user data
copy	Copy function for the user data (can be NULL)
release	Release function for the user data (can be NULL)

	)

inherited

Set user data with copy and release functions.

Parameters

data	Pointer to user data
copy	Copy function for the user data (can be NULL)
release	Release function for the user data (can be NULL)

◆ userData() [1/2]

void* deepstream::UserMetadata::userData ( ) const

inherited

Get the user data pointer.

◆ userData() [2/2]

void* deepstream::UserMetadata::userData ( ) const

inherited

Get the user data pointer.
