sg_file_seek()

void sg_file_seek	(	sg_file_t	fd,
		sg_offset_t	offset,
		int	origin
	)

Set the file position indicator in the sg_file_t by adding offset bytes to the position specified by origin (either SEEK_SET, SEEK_CUR, or SEEK_END).

Parameters

fd	: file object that identifies the stream
offset	: number of bytes to offset from origin
origin	: Position used as reference for the offset. It is specified by one of the following constants defined in <stdio.h> exclusively to be used as arguments for this function (SEEK_SET = beginning of file, SEEK_CUR = current position of the file pointer, SEEK_END = end of file)

Copy a file to another location on a remote host.

Parameters

file	: the file to move
host	: the remote host where the file has to be copied
fullpath	: the complete path destination on the remote host

Returns

If successful, the function returns 0. Otherwise, it returns -1.

sg_file_rmove()

int sg_file_rmove	(	sg_file_t	file,

Parameters

file	: the file to move
host	: the remote host where the file has to be moved
fullpath	: the complete path destination on the remote host

Returns

If successful, the function returns 0. Otherwise, it returns -1.
