◆ crypto_msg

#define crypto_msg (   flags,
do { \
crypto_print_openssl_errors(nonfatal(flags)); \
msg((flags), __VA_ARGS__); \
} while (false)
list flags
static unsigned int nonfatal(const unsigned int err)
Convert fatal errors to nonfatal, don&#39;t touch other errors.
Definition: error.h:385

Retrieve any OpenSSL errors, then print the supplied error message.

This is just a convenience wrapper for often occurring situations.

flagsFlags to indicate error type and priority.
formatFormat string to print.
formatargs (optional) arguments for the format string.
