SSL_get_ex_data_X509_STORE_CTX_idx(3)
NAME
  SSL_get_ex_data_X509_STORE_CTX_idx - Get ex_data index to access SSL
  structure from X509_STORE_CTX

SYNOPSIS
  #include <openssl/ssl.h>

  int SSL_get_ex_data_X509_STORE_CTX_idx(
	  void );

DESCRIPTION
  The SSL_get_ex_data_X509_STORE_CTX_idx() function returns the index number
  under which the pointer to the SSL object is stored into the X509_STORE_CTX
  object.

NOTES
  Whenever an 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 the
  SSL_get_ex_data_X509_STORE_CTX_idx() function. The index value is set when
  the SSL_get_ex_data_X509_STORE_CTX_idx() function 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.

EXAMPLES
  The index returned from the SSL_get_ex_data_X509_STORE_CTX_idx() function
  allows you to access the SSL object for the connection to be accessed
  during the verify_callback() function when checking the peers certificate.
  Check the example in SSL_CTX_set_verify(3).
