Function SCIPincludeReaderBasic 

pub unsafe extern "C" fn SCIPincludeReaderBasic(
    scip: *mut SCIP,
    readerptr: *mut *mut SCIP_READER,
    name: *const c_char,
    desc: *const c_char,
    extension: *const c_char,
    readerdata: *mut SCIP_READERDATA,
) -> SCIP_RETCODE

creates a reader and includes it in SCIP. All non-fundamental (or optional) callbacks will be set to NULL. Optional callbacks can be set via specific setter functions, see SCIPsetReaderCopy(), SCIPsetReaderFree(), SCIPsetReaderRead(), SCIPsetReaderWrite().

@return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref SCIP_Retcode “SCIP_RETCODE” for a complete list of error codes.

@pre This method can be called if SCIP is in one of the following stages: - \ref SCIP_STAGE_INIT - \ref SCIP_STAGE_PROBLEM

@note if you want to set all callbacks with a single method call, consider using SCIPincludeReader() instead
