152.SH "DESCRIPTION"
153.IX Header "DESCRIPTION"
154Several OpenSSL structures can have application specific data attached to them.
155These functions are used internally by OpenSSL to manipulate application
156specific data attached to a specific structure.
157.PP
158These functions should only be used by applications to manipulate
159\&\fB\s-1CRYPTO_EX_DATA\s0\fR structures passed to the \fB\f(BInew_func()\fB\fR, \fB\f(BIfree_func()\fB\fR and
160\&\fB\f(BIdup_func()\fB\fR callbacks: as passed to \fB\f(BIRSA_get_ex_new_index()\fB\fR for example.
161.PP
162\&\fB\f(BICRYPTO_set_ex_data()\fB\fR is used to set application specific data, the data is
163supplied in the \fBarg\fR parameter and its precise meaning is up to the
164application.
165.PP
166\&\fB\f(BICRYPTO_get_ex_data()\fB\fR is used to retrieve application specific data. The data
167is returned to the application, this will be the same value as supplied to
168a previous \fB\f(BICRYPTO_set_ex_data()\fB\fR call.
169.SH "RETURN VALUES"
170.IX Header "RETURN VALUES"
171\&\fB\f(BICRYPTO_set_ex_data()\fB\fR returns 1 on success or 0 on failure.
172.PP
173\&\fB\f(BICRYPTO_get_ex_data()\fB\fR returns the application data or 0 on failure. 0 may also
174be valid application data but currently it can only fail if given an invalid \fBidx\fR
175parameter.
176.PP
177On failure an error code can be obtained from \fIERR_get_error\fR\|(3).
