int
read(
Json* result,
std::istream& input);Description
Load to the specified result a value‐semantic representation of the JSON text in the specified input. Optionally specify an errorDescription that, if an error occurs, is loaded with a description of the error. Optionally specify options which allow altering the maximum nesting depth. Return 0 on success, and a non‐zero value if input does not consist of valid JSON text or an error occurs when reading from input. If options.allowTrailingText() is false (the default), then an error will be reported if a valid JSON text is followed by any text that does not consist solely of white‐space characters. If options.allowTrailingText() is true, then this function will return success where a valid JSON document is followed by additional text as long as that text is separated from the valid JSON by a delimiter character (i.e., either the JSON text ends in a delimiter, or the text that follows starts with a delimiter). Here, delimiters are white‐space characters, [],],{,},,, or ".
Return Value
0 on success, and a non‐zero value otherwise
