Inheritance diagram for FST::fst_error:

Public Member Functions
	fst_error (const std::string &_err, const int _errcode=0)
	Constructs the error, prefixing _err with "[FST_ERROR!] " for the inherited std::runtime_error::what() message.
int	code () const
	returns the numeric error code supplied at construction (0 if none was given)

Private Attributes
const int	_code
	numeric error code supplied at construction

Detailed Description

FST4 specific error passing class.

Derives from std::runtime_error, so a caller that catches std::exception (or std::runtime_error) catches every error FST4 throws; what() returns the message supplied at construction, prefixed with "[FST_ERROR!] ". The optional numeric code is diagnostic only – no FST4 component branches on it, and the same code may be reused by unrelated components, so recovery logic must not depend on it.

Examples

demo10.cpp, demo52t.cpp, and demo55.cpp.
