GFS_PIO_RECVFILE
NAMESYNOPSIS
DESCRIPTION
RETURN VALUES
SEE ALSO
NAME
gfs_pio_recvfile - receive a Gfarm file to local machine
SYNOPSIS
#include <gfarm/gfarm.h>
|
gfarm_error_t gfs_pio_recvfile(GFS_File r_gf , gfarm_off_t r_off , int w_fd , gfarm_off_t w_off , gfarm_off_t len , gfarm_off_t * recvp ); |
DESCRIPTION
Receives len bytes of data from the position specified by the offset r_off in a Gfarm file r_gf , to the position specified by the offset w_off of a local file which is pointed by a file descriptor w_fd . If len is -1, this function transfers until the end of the file. The transfered bytes will be stored to the memory pointed by recvp when recvp is not NULL . If len is a positive value, and the value pointed by recvp is less than len , that means the transfer reached EOF.
RETURN VALUES
GFARM_ERR_NO_ERROR
The function terminated successfully.
GFARM_ERR_OPERATION_NOT_PERMITTED
gf does not specify a regular file.
GFARM_ERR_BAD_FILE_DESCRIPTOR
The file descripter specified by gf is not a valid or is not open for reading.
GFARM_ERR_NO_FILE_SYSTEM_NODE
There is no available file system node.
GFARM_ERR_NO_MEMORY
Insufficient memory was available.
Others
An error except the above occurred. The reason is shown by gfarm_error_string (3).
