gfs_pio_seek

NAME

gfs_pio_seek - reposition a stream

SYNOPSIS

#include <gfarm/gfarm.h>

char *gfs_pio_seek (GFS_File gf, file_offset_t offset, int whence, file_offset_t * result);

DESCRIPTION

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 0, 1, or 2, 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

NULL

The function terminated successfully.

GFARM_ERR_NO_MEMORY
