.Sh DESCRIPTION
These functions handle application specific data in
.Vt X509_STORE_CTX
structures.
Their usage is identical to that of
.Xr RSA_get_ex_new_index 3 ,
.Xr RSA_set_ex_data 3 ,
and
.Xr RSA_get_ex_data 3 .
.Pp
This mechanism is used internally by the
.Xr ssl 3
library to store the
.Vt SSL
structure associated with a verification operation in an
.Vt X509_STORE_CTX
structure.
.Sh SEE ALSO
.Xr RSA_get_ex_new_index 3
.Sh HISTORY
.Fn X509_STORE_CTX_get_ex_new_index ,
.Fn X509_STORE_CTX_set_ex_data ,
and
.Fn X509_STORE_CTX_get_ex_data
first appeared in SSLeay 0.9.0 and have been available since
.Ox 2.4 .
