void FileServerFd_Clear

(

FileServer *

p

)

Parameters

name	Interest name.

Return values

NULL	filename is invalid or does not match a mount.
FileServer_NotFound	file does not exist; do not Unref this value.

FileServerFd_PrepareMetadata_()

uint32_t FileServerFd_PrepareMetadata_	(	FileServer *	p,
		FileServerFd *	entry
	)

FileServerFd_Unref()

void FileServerFd_Unref	(	FileServer *	p,
		FileServerFd *	entry
	)

void FileServerFd_WriteMetadata	(	FileServerFd *	entry,
		struct iovec *	iov,
		int	iovcnt
	)

Write metadata packet.

Parameters

entry	a valid FileServerFd entry.
iov	Content iov, must match the length from FileServerFd_PrepareMetadata .
