.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Several OpenSSL structures can have application specific data attached to them.
These functions are used internally by OpenSSL to manipulate application
specific data attached to a specific structure.
.PP
\&\fISSL_get_ex_new_index()\fR is used to register a new index for application
specific data.
.PP
\&\fISSL_set_ex_data()\fR is used to store application data at \fBarg\fR for \fBidx\fR into
the \fBssl\fR object.
.PP
\&\fISSL_get_ex_data()\fR is used to retrieve the information for \fBidx\fR from
\&\fBssl\fR.
.PP
A detailed description for the \fB*\f(BI_get_ex_new_index()\fB\fR functionality
can be found in RSA_get_ex_new_index(3).
The \fB*\f(BI_get_ex_data()\fB\fR and \fB*\f(BI_set_ex_data()\fB\fR functionality is described in
CRYPTO_set_ex_data(3).
.SH "EXAMPLES"
.IX Header "EXAMPLES"
An example on how to use the functionality is included in the example
\&\fIverify_callback()\fR in SSL_CTX_set_verify(3).
