处理错误

说明

Many libbson functions report errors by returning NULL or -1 and filling out a bson_error_t structure with an error domain, error code, and message.

error.domain 生成错误的子系统的名称。
error.code 是特定于域的错误类型。
error.message 描述了错误。

某些错误代码与其他错误代码重叠；请务必同时检查域和代码以确定错误类型。

`BSON_ERROR_JSON`	`BSON_JSON_ERROR_READ_CORRUPT_JS` `BSON_JSON_ERROR_READ_INVALID_PARAM` `BSON_JSON_ERROR_READ_CB_FAILURE`	bson_json_reader_t tried to parse invalid MongoDB Extended JSON. Tried to parse a valid JSON document that is invalid as MongoDBExtended JSON. An internal callback failure during JSON parsing.
`BSON_ERROR_READER`	`BSON_ERROR_READER_BADFD`	bson_json_reader_new_from_file could not open the file.
