SYNOPSIS

int
TYPE_get_ex_new_index(long argl,
void *argp, CRYPTO_EX_new
*new_func, CRYPTO_EX_dup *dup_func,

DESCRIPTION
In the description here, TYPE is used a placeholder for any of the OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3).
These functions handle application-specific data for OpenSSL data structures.
TYPE_get_ex_new_index()
is a macro that calls
CRYPTO_get_ex_new_index(3) with the correct index value.
TYPE_set_ex_data()
is a function that calls
CRYPTO_set_ex_data(3) with an offset into the opaque exdata
part of the TYPE object.
TYPE_get_ex_data()
is a function that calls
CRYPTO_get_ex_data(3) with an offset into the opaque exdata
part of the TYPE object.
