Enumeration Type Documentation

uhd_error

enum uhd_error

UHD error codes.

Each error code corresponds to a specific uhd::exception, with extra codes corresponding to a boost::exception, std::exception, and a catch-all for everything else. When an internal C++ function throws an exception, UHD converts it to one of these error codes to return on the C level.

Function Documentation

uhd_get_last_error()

uhd_error uhd_get_last_error	(	char *	error_out,
		size_t	strbuffer_len
	)

Return the last error string reported by UHD.

Functions that do not take in UHD structs/handles will place any error strings into a buffer that can be queried with this function. Functions that do take in UHD structs/handles will place their error strings in both locations.
