Constructs a :class:fmt::SystemError object with a description formatted with fmt::format_system_error. message and additional arguments passed into the constructor are formatted similarly to fmt::format.

Example**::

This throws a SystemError with the description cannot open file 'madeup': No such file or directory or similar (system message may vary). const char *filename = "madeup"; std::FILE *file = std::fopen(filename, "r"); if (!file) throw fmt::SystemError(errno, "cannot open file '{}'", filename);
