fmt::SystemError::SystemError ( )

inlineprotected

fmt::SystemError::SystemError ( int  error_code, CStringRef  message  )

inline

Constructs a :class:fmt::SystemError object with the description of the form

.. parsed-literal:: <message>*: *<system-message>*

where *<message>* is the formatted message and *<system-message>* is the system message corresponding to the error code. error_code* is a system error code as given by errno. If error_code is not a valid error code such as -1, the system message may look like "Unknown error -1" and is platform-dependent.

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);
