mi_integer mi_file_seek(fd, offset, whence)

		mi_integer fd;

		mi_integer offset;

		mi_integer whence; 


fd
is the file descriptor of the file to be read. It is obtained by a previous call to mi_file_open(). 

off
is the offset. It describes where to seek in the object. Its value depends on the value of whence. 



If whence is MI_LO_SEEK_SET, the offset is measured relative to the beginning of the object



If whence is MI_LO_SEEK_CUR, the offset is relative to the current position in the object.



If whence is MI_LO_SEEK_END, the offset is relative to the end of the file.

whence
determines how the offset is interpreted and is one of the following values:



MI_LO_SEEK_SET



MI_LO_SEEK_CUR



MI_LO_SEEK_END
