ASN1 object utilities
SYNOPSIS
#include <openssl/asn1t.h>
DECLARE_ASN1_FUNCTIONS(type)
IMPLEMENT_ASN1_FUNCTIONS(stname)
typedef struct ASN1_ITEM_st ASN1_ITEM;
extern const ASN1_ITEM TYPE_it;
TYPE *TYPE_new(void);
TYPE *TYPE_dup(TYPE *a);
void TYPE_free(TYPE *a);
int TYPE_print_ctx(BIO *out, TYPE *a, int indent, const ASN1_PCTX *pctx);
DESCRIPTION
In the description below, TYPE is used as a placeholder for any of the
OpenSSL datatypes, such as X509.
The OpenSSL ASN1 parsing library templates are like a data-driven
bytecode interpreter. Every ASN1 object as a global variable, TYPE_it,
that describes the item such as its fields. (On systems which cannot
export variables from shared libraries, the global is instead a
function which returns a pointer to a static variable.
The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files to
generate the function declarations.
The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file to
generate the function bodies.
TYPE_new() allocates an empty object of the indicated type. The object
returned must be released by calling TYPE_free().
TYPE_dup() copies an existing object.
TYPE_free() releases the object and all pointers and sub-objects within
it.
TYPE_print_ctx() prints the object a on the specified BIO out. Each
line will be prefixed with indent spaces. The pctx specifies the
printing context and is for internal use; use NULL to get the default
behavior. If a print function is user-defined, then pass in any pctx
down to any nested calls.
RETURN VALUES
TYPE_new() and TYPE_dup() return a pointer to the object or NULL on
failure.
TYPE_print_ctx() returns 1 on success or zero on failure.
