                     15: is an offset in bytes relative to the position specified by

                     30: .I fseek
                     31: will be 0 if successful, a system error code otherwise.

                     33: .PP
                     34: .I Ftell
                     35: returns the current position of the file associated with the specified
                     36: logical unit. The value is an offset, in bytes, from the beginning of the file.
                     37: If the value returned is negative, it indicates an error and will be
                     38: the negation of the system error code. (See perror(3F))
