156.IX Header "DESCRIPTION"
157Several OpenSSL structures can have application specific data attached to them.
158These functions are used internally by OpenSSL to manipulate application
159specific data attached to a specific structure.
160.PP
161\&\fISSL_get_ex_new_index()\fR is used to register a new index for application
162specific data.
163.PP
164\&\fISSL_set_ex_data()\fR is used to store application data at \fBarg\fR for \fBidx\fR into
165the \fBssl\fR object.
166.PP
167\&\fISSL_get_ex_data()\fR is used to retrieve the information for \fBidx\fR from
168\&\fBssl\fR.
169.PP
170A detailed description for the \fB*\f(BI_get_ex_new_index()\fB\fR functionality
171can be found in \fIRSA_get_ex_new_index\fR\|(3).
172The \fB*\f(BI_get_ex_data()\fB\fR and \fB*\f(BI_set_ex_data()\fB\fR functionality is described in
173\&\fICRYPTO_set_ex_data\fR\|(3).
174.SH "EXAMPLES"
175.IX Header "EXAMPLES"
176An example on how to use the functionality is included in the example
177\&\fIverify_callback()\fR in \fISSL_CTX_set_verify\fR\|(3).
