The function gcry_strerror
returns a pointer to a statically
allocated string containing a description of the error code contained
in the error value err. This string can be used to output a
diagnostic message to the user.
The function gcry_strsource
returns a pointer to a statically
allocated string containing a description of the error source
contained in the error value err. This string can be used to
output a diagnostic message to the user.
The following example illustrates the use of the functions described above:
{ gcry_cipher_hd_t handle; gcry_error_t err = 0; err = gcry_cipher_open (&handle, GCRY_CIPHER_AES, GCRY_CIPHER_MODE_CBC, 0); if (err) { fprintf (stderr, "Failure: %s/%s\n", gcry_strsource (err), gcry_strerror (err)); } }
