.SH DESCRIPTION
.IX Header "DESCRIPTION"
This type is a tuple of integer and pointer.
It's a generic type used as a generic descriptor, its exact meaning
being defined by how it's used.
Arrays of this type are passed between the OpenSSL libraries and the
providers, and must be terminated with a tuple where the integer is
zero and the pointer NULL.
.PP
This is currently mainly used for the return value of the provider's error
reason strings array, see "Provider Functions" in \fBprovider\-base\fR\|(7).
