lseek64(3) is a C library function that repositions the file offset of an open file descriptor to a specified position. It uses a 64-bit type for the offset and is available only when _LARGEFILE64_SOURCE is defined.
lseek64 (3) is a library function that repositions the offset of a 64-bit file to a specified position. It is an alias for llseek (2), which uses a 64-bit type for the offset parameter. See also lseek (2), llseek (2), and _llseek (2).

The lseek64 () function is identical to the lseek () function except that it uses the larger off64_t in order to manipulate the file position of files that are larger than 2 gigabytes.
lseek64 () is a library function that repositions the file offset of an open file descriptor to a specified value. It uses a 64-bit type and is available only when _LARGEFILE64_SOURCE is defined.
lseek64 (3) is a function to reposition the offset of a 64-bit file in Linux. It is an alias for llseek (2), which uses a 64-bit type loff_t. See the syntax, description, attributes, and related functions.
The library routine lseek64 () uses a 64-bit type even when off_t is a 32-bit type. Its prototype (and the type off64_t) is available only when one compiles with
