 * \param verbose 1 - print found value to stderr, 0 - don't
 * \param *FileBuffer pointer to buffer structure
 * \param name Name of value in file (at least 3 chars!)
 * \param sequential 1 - do not reset file pointer to begin of file, 0 - set to beginning
 *        (if file is sequentially parsed this can be way faster! However, beware of multiple values per line, as whole line is read -
 *         best approach: 0 0 0 1 (not resetted only on last value of line) - and of yth, which is now
 *         counted from this unresetted position!)
 * \param xth Which among a number of parameters it is (in grid case it's row number as grid is read as a whole!)
 * \param yth In grid case specifying column number, otherwise the yth \a name matching line
 * \param type Type of the Parameter to be read
 * \param value address of the value to be read (must have been allocated)
 * \param repetition determines, if the keyword appears multiply in the config file, which repetition shall be parsed, i.e. 1 if not multiply
 * \param critical necessity of this keyword being specified (optional, critical)
 * \return 1 - found, 0 - not found
