NAME¶gfs_pio_recvfile - receive a Gfarm file to local machine
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.
