|SSL_GET_EX_DATA_X509_STORE_CTX_IDX(3)||Library Functions Manual||SSL_GET_EX_DATA_X509_STORE_CTX_IDX(3)|
SSL_get_ex_data_X509_STORE_CTX_idx() returns the index number under which the pointer to the SSL object is stored into the X509_STORE_CTX object.
Whenever a X509_STORE_CTX object is created
for the verification of the peer's certificate during a handshake, a pointer
to the SSL object is stored into the
X509_STORE_CTX object to identify the connection
affected. To retrieve this pointer the
function can be used with the correct index. This index is globally the same
for all X509_STORE_CTX objects and can be retrieved
index value is set when
SSL_get_ex_data_X509_STORE_CTX_idx() is first called
either by the application program directly or indirectly during other SSL
setup functions or during the handshake.
The value depends on other index values defined for X509_STORE_CTX objects before the SSL index is created.
SSL_get_ex_data_X509_STORE_CTX_idx() provides access to SSL object for the connection during the
verify_callback() when checking the peer's certificate. Please check the example in SSL_CTX_set_verify(3).
SSL_get_ex_data_X509_STORE_CTX_idx() first appeared in SSLeay 0.9.1 and has been available since OpenBSD 2.6.
