gfs_pio_seek3
Reposition a stream
Usage
#include <gfarm/gfarm.h>
gfarm_error_t gfs_pio_seek(GFS_File gf, gfarm_off_t offset, int whence, gfarm_off_t * result);
Overview
The gfs_pio_seek() function sets the file position indicator for the file gf. The new position, measured in bytes, is obtained by adding offset bytes to the position specified by whence. If whence is set to GFARM_SEEK_SET, GFARM_SEEK_CUR, or GFARM_SEEK_END, the offset is relative to the start of the file, the current position indicator, or end-of-file, respectively. When result is not NULL, the new position returns to the address pointed by result.
Return values
GFARM_ERR_NO_ERROR
The function terminated successfully.
GFARM_ERR_NO_MEMORY
Insufficient memory was available.
GFARM_ERR_INVALID_ARGUMENT
Specified whence or offset is invalid.
Other
An error except the above occurred. The reason is shown by gfarm_error_string(3).
