DESCRIPTION

99       In the description below, TYPE is used as a placeholder for any of the
100       OpenSSL datatypes, such as X509.
101
102       The OpenSSL ASN1 parsing library templates are like a data-driven
103       bytecode interpreter.  Every ASN1 object as a global variable, TYPE_it,
104       that describes the item such as its fields.  (On systems which cannot
105       export variables from shared libraries, the global is instead a
106       function which returns a pointer to a static variable.
107
108       The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files to
109       generate the function declarations.
110
111       The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file to
112       generate the function bodies.
113
114       TYPE_new() allocates an empty object of the indicated type.  The object
115       returned must be released by calling TYPE_free().
116
117       TYPE_dup() copies an existing object.
118
119       TYPE_free() releases the object and all pointers and sub-objects within
120       it.
121
122       TYPE_print_ctx() prints the object a on the specified BIO out.  Each
123       line will be prefixed with indent spaces.  The pctx specifies the
124       printing context and is for internal use; use NULL to get the default
125       behavior.  If a print function is user-defined, then pass in any pctx
126       down to any nested calls.
127

RETURN VALUES

129       TYPE_new() and TYPE_dup() return a pointer to the object or NULL on
130       failure.
131
132       TYPE_print_ctx() returns 1 on success or zero on failure.
