MONGOC_STRUCTURED_LOG_OPTS_SET_MAX_DOCUMENT_LENGTH(3) libmongoc MONGOC_STRUCTURED_LOG_OPTS_SET_MAX_DOCUMENT_LENGTH(3)

SYNOPSIS

bool
mongoc_structured_log_opts_set_max_document_length (mongoc_structured_log_opts_t *opts,


                                                    size_t max_document_length);


Sets a maximum length for BSON documents that appear serialized in JSON form as part of a structured log message.

Serialized JSON will be truncated at this limit, interpreted as a count of UTF-8 encoded bytes. Truncation will be indicated with a ... suffix, the length of which is not included in the max document length. If truncation at the exact indicated length would split a valid UTF-8 sequence, we instead truncate the document earlier at the nearest boundary between code points.

PARAMETERS

  • opts: Structured log options, allocated with mongoc_structured_log_opts_new() <>.
  • max_document_length: Maximum length for each embedded JSON document, in bytes, not including an ellipsis (...) added to indicate truncation. Values near or above INT_MAX will be rejected.

RETURNS

Returns true on success, or false if the supplied maximum length is too large.
