Function Documentation

int fd_create_file	(	trn_file_ops_t *	fops,
		void *	data
	)

Create a file from fops and data.

Data will be sent to the various functions in fops. Data will usually contain the underlying handle (like the fd for bsd)

int fd_dup2	(	int	oldfd,
		int	newfd
	)

Duplicates oldfd, and all its associated locks, into newfd.

Newfd is closed if necessary.

trn_file_t* fd_file_get

(

int

fd

)

Get the file structure from a given fd, and increment its rc.

Any call to this function needs an equivalent call to fd_file_put.
