Function libcqdb::cqdb_writer

#[no_mangle]pub extern "C" fn cqdb_writer(fp: *mut FILE, flag: c_int) -> *mut cqdb_writer_t

Create a new CQDB writer on a seekable stream.

This function initializes a database on the seekable stream and returns the pointer to a ::cqdb_writer_t instanceto write the database. The stream must have the writable and binary flags. The database creation flag must be zero except when the reverse lookup array is unnecessary; specifying ::CQDB_ONEWAY flag will save the storage space for the reverse lookup array. Once calling this function, one should avoid accessing the seekable stream directly until calling cqdb_writer_close().
