+=head1 NAME
+
+ASN1_INTEGER_new, ASN1_INTEGER_free - ASN1_INTEGER allocation functions
+
+=head1 SYNOPSIS
+
+=for openssl generic
+
+ #include <openssl/asn1.h>
+
+ ASN1_INTEGER *ASN1_INTEGER_new(void);
+ void ASN1_INTEGER_free(ASN1_INTEGER *a);
+
+=head1 DESCRIPTION
+
+ASN1_INTEGER_new() returns an allocated B<ASN1_INTEGER> structure.
+
+ASN1_INTEGER_free() frees up a single B<ASN1_INTEGER> object.
+
+B<ASN1_INTEGER> structure representing the ASN.1 INTEGER type
+
+=head1 RETURN VALUES
+
+ASN1_INTEGER_new() return a valid B<ASN1_INTEGER> structure or NULL
+if an error occurred.
+
+ASN1_INTEGER_free() does not return a value.
