create a parse error exception

Parameters

[in]	id_	the id of the exception
[in]	pos	the position where the error occurred (or with chars_read_total=0 if the position cannot be determined)
[in]	what_arg	the explanatory string

Returns

parse_error object

Field Documentation

byte

const std::size_t detail::parse_error::byte

byte index of the parse error

The byte index of the last read character in the input file.

Note

For an input with n bytes, 1 is the index of the first character and n+1 is the index of the terminating null byte or the end of file. This also holds true when reading a byte vector (CBOR or MessagePack).

Definition at line 4664 of file json.hpp.

id

const int detail::exception::id

inherited

the id of the exception

m
