Schily's LIBRARY FUNCTIONS FILEPOS(3)
filepos() - returns the logical position in a file
filepos() returns the current file position as an offset in
bytes from the beginning of the file. This is the position
of the next byte to be read or written.
Returns the current offset into file f.
The numbering of bytes in a file starts at 0. For byte
sequential devices, such as a terminal, the value returned
will be the number of bytes read or written from the current
file, unless a seek call is issued which changes the logical
position but does not affect the device.
File positions may be set to arbitrary values (via
fileseek() ) and are only used by the file system when
actual reading or writing occur.
Normally, the file position is incremented by the amount of
data transferred for each sequential read or write.
