+=head1 DESCRIPTION
+
+An B<EC_POINT> structure represents a point on a curve. A new point is
+constructed by calling the function EC_POINT_new() and providing the
+B<group> object that the point relates to.
+
+EC_POINT_free() frees the memory associated with the B<EC_POINT>.
+if B<point> is NULL nothing is done.
+
+EC_POINT_clear_free() destroys any sensitive data held within the EC_POINT and
+then frees its memory. If B<point> is NULL nothing is done.
+
+EC_POINT_copy() copies the point B<src> into B<dst>. Both B<src> and B<dst>
+must use the same B<EC_METHOD>.
+
+EC_POINT_dup() creates a new B<EC_POINT> object and copies the content from
+B<src> to the newly created B<EC_POINT> object.
+
+EC_POINT_method_of() obtains the B<EC_METHOD> associated with B<point>.
+
+A valid point on a curve is the special point at infinity. A point is set to
+be at infinity by calling EC_POINT_set_to_infinity().
+
+The affine co-ordinates for a point describe a point in terms of its x and y
+position. The functions EC_POINT_set_affine_coordinates_GFp() and
+EC_POINT_set_affine_coordinates_GF2m() set the B<x> and B<y> co-ordinates for
+the point B<p> defined over the curve given in B<group>.
+
+As well as the affine co-ordinates, a point can alternatively be described in
+terms of its Jacobian projective co-ordinates (for Fp curves only). Jacobian
+projective co-ordinates are expressed as three values x, y and z. Working in
+this co-ordinate system provides more efficient point multiplication
+operations.  A mapping exists between Jacobian projective co-ordinates and
+affine co-ordinates. A Jacobian projective co-ordinate (x, y, z) can be written
+as an affine co-ordinate as (x/(z^2), y/(z^3)). Conversion to Jacobian
+projective from affine co-ordinates is simple. The co-ordinate (x, y) is mapped
+to (x, y, 1). To set or get the projective co-ordinates use
+EC_POINT_set_Jprojective_coordinates_GFp() and
+EC_POINT_get_Jprojective_coordinates_GFp() respectively.
+
+Points can also be described in terms of their compressed co-ordinates. For a
+point (x, y), for any given value for x such that the point is on the curve
+there will only ever be two possible values for y. Therefore a point can be set
+using the EC_POINT_set_compressed_coordinates_GFp() and
+EC_POINT_set_compressed_coordinates_GF2m() functions where B<x> is the x
+co-ordinate and B<y_bit> is a value 0 or 1 to identify which of the two
+possible values for y should be used.
+
+In addition B<EC_POINT> can be converted to and from various external
+representations. The octet form is the binary encoding of the B<ECPoint>
+structure (as defined in RFC5480 and used in certificates and TLS records):
+only the content octets are present, the B<OCTET STRING> tag and length are
+not included. B<BIGNUM> form is the octet form interpreted as a big endian
+integer converted to a B<BIGNUM> structure. Hexadecimal form is the octet
+form converted to a NULL terminated character string where each character
+is one of the printable values 0-9 or A-F (or a-f).
+
+The functions EC_POINT_point2oct(), EC_POINT_oct2point(), EC_POINT_point2bn(),
+EC_POINT_bn2point(), EC_POINT_point2hex() and EC_POINT_hex2point() convert from
+and to EC_POINTs for the formats: octet, BIGNUM and hexadecimal respectively.
+
+The function EC_POINT_point2oct() must be supplied with a buffer long enough to
+store the octet form. The return value provides the number of octets stored.
+Calling the function with a NULL buffer will not perform the conversion but
+will still return the required buffer length.
+
+The function EC_POINT_point2buf() allocates a buffer of suitable length and
+writes an EC_POINT to it in octet format. The allocated buffer is written to
+B<*pbuf> and its length is returned. The caller must free up the allocated
+buffer with a call to OPENSSL_free(). Since the allocated buffer value is
+written to B<*pbuf> the B<pbuf> parameter B<MUST NOT> be B<NULL>.
+
+The function EC_POINT_point2hex() will allocate sufficient memory to store the
+hexadecimal string. It is the caller's responsibility to free this memory with
+a subsequent call to OPENSSL_free().
+
+=head1 RETURN VALUES
+
+EC_POINT_new() and EC_POINT_dup() return the newly allocated EC_POINT or NULL
+on error.
+
+The following functions return 1 on success or 0 on error: EC_POINT_copy(),
+EC_POINT_set_to_infinity(), EC_POINT_set_Jprojective_coordinates_GFp(),
+EC_POINT_get_Jprojective_coordinates_GFp(),
+EC_POINT_set_affine_coordinates_GFp(), EC_POINT_get_affine_coordinates_GFp(),
+EC_POINT_set_compressed_coordinates_GFp(),
+EC_POINT_set_affine_coordinates_GF2m(), EC_POINT_get_affine_coordinates_GF2m(),
+EC_POINT_set_compressed_coordinates_GF2m() and EC_POINT_oct2point().
+
+EC_POINT_method_of returns the EC_METHOD associated with the supplied EC_POINT.
+
+EC_POINT_point2oct() and EC_point2buf() return the length of the required
+buffer or 0 on error.
+
+EC_POINT_point2bn() returns the pointer to the BIGNUM supplied, or NULL on
+error.
+
+EC_POINT_bn2point() returns the pointer to the EC_POINT supplied, or NULL on
+error.
+
+EC_POINT_point2hex() returns a pointer to the hex string, or NULL on error.
+
+EC_POINT_hex2point() returns the pointer to the EC_POINT supplied, or NULL on
+error.
