SYNOPSIS
#include <openssl/ssl.h>
int SSL_get_ex_data_X509_STORE_CTX_idx(void);
DESCRIPTION
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.NOTES
Whenever a X509_STORE_CTX object is created for the verification of the peers 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 X509_STORE_CTX_get_ex_data() function can be used with the correct index. This index is globally the same for all X509_STORE_CTX objects and can be retrieved using SSL_get_ex_data_X509_STORE_CTX_idx(). The 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.
RETURN VALUES
- >=0
- The index value to access the pointer.
- <0
- An error occurred, check the error stack for a detailed error message.
