This sub\-module provides 64\-bit variants of the channel functions that manipulate file positions and file sizes\&. By representing positions and sizes by 64\-bit integers (type .B int64 ) instead of regular integers (type .B int ), these alternate functions allow operating on files whose sizes are greater than .B max_int \&. .sp .sp .sp .I val seek_out : .B Pervasives.out_channel -> int64 -> unit .sp .sp .I val pos_out : .B Pervasives.out_channel -> int64 .sp .sp .I val out_channel_length : .B Pervasives.out_channel -> int64 .sp .sp .I val seek_in : .B Pervasives.in_channel -> int64 -> unit .sp .sp .I val pos_in : .B Pervasives.in_channel -> int64 .sp .sp .I val in_channel_length : .B Pervasives.in_channel -> int64 .sp .sp
