JSON_NO_IO

#define JSON_NO_IO

When defined, headers <cstdio>, <ios>, <iosfwd>, <istream>, and <ostream> are not included and parse functions relying on these headers are excluded. This is relevant for environment where these I/O functions are disallowed for security reasons (e.g., Intel Software Guard Extensions (SGX)).

Default definition

By default, #!cpp JSON_NO_IO is not defined.

#undef JSON_NO_IO
