glTexCoordPointer(3G)
NAME
  glTexCoordPointer - define an array of texture coordinates

SYNOPSIS
  void glTexCoordPointer(
	  GLint size,
	  GLenum type,
	  GLsizei stride,
	  const GLvoid *pointer );

PARAMETERS
  size
      Specifies the number of coordinates per array element. Must be 1, 2, 3
      or 4. The initial value is 4.

  type
      Specifies the data type of each texture coordinate. Symbolic constants
      GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted. The initial
      value is GL_FLOAT.

  stride
      Specifies the byte offset between consecutive array elements. If stride
      is 0, the array elements are understood to be tightly packed. The
      initial value is 0.

  pointer
      Specifies a pointer to the first coordinate of the first element in the
      array.  The initial value is 0.

DESCRIPTION
  glTexCoordPointer() specifies the location and data of an array of texture
  coordinates to use when rendering.  size specifies the number of
  coordinates per element, and must be 1, 2, 3, or 4.  type specifies the
  data type of each texture coordinate and stride specifies the byte stride
  from one array element to the next allowing vertexes and attributes to be
  packed into a single array or stored in separate arrays. (Single-array
  storage may be more efficient on some implementations; see
  glInterleavedArrays().) When a texture coordinate array is specified, size,
  type, stride, and pointer are saved client-side state.

  To enable and disable the texture coordinate array, call
  glEnableClientState() and glDisableClientState() with the argument
  GL_TEXTURE_COORD_ARRAY. If enabled, the texture coordinate array is used
  when glDrawArrays(), glDrawElements(), glDrawRangeElements() or
  glArrayElement() is called.

  Use glDrawArrays() to construct a sequence of primitives (all of the same
  type) from prespecified vertex and vertex attribute arrays.  Use
  glArrayElement() to specify primitives by indexing vertexes and vertex
  attributes and glDrawElements() to construct a sequence of primitives by
  indexing vertexes and vertex attributes.

NOTES
  glTexCoordPointer() is available only if the GL version is 1.1 or greater.

  The texture coordinate array is initially disabled and it won't be accessed
  when glArrayElement(), glDrawElements(), glDrawRangeElements(), or
  glDrawArrays() is called.

  Execution of glTexCoordPointer() is not allowed between the execution of
  glBegin() and the corresponding execution of glEnd(), but an error may or
  may not be generated. If no error is generated, the operation is undefined.

  glTexCoordPointer() is typically implemented on the client side with no
  protocol.

  The texture coordinate array parameters are client-side state and are
  therefore not saved or restored by glPushAttrib() and glPopAttrib(). Use
  glPushClientAttrib() and glPopClientAttrib() instead.

  When the GL_ARB_imaging extension is supported, glTexCoordPointer() updates
  the texture coordinate array state of the active client texture unit,
  specified with glClientActiveTextureARB().

ERRORS
  GL_INVALID_VALUE is generated if size is not 1, 2, 3, or 4.

  GL_INVALID_ENUM is generated if type is not an accepted value.

  GL_INVALID_VALUE is generated if stride is negative.

ASSOCIATED GETS
       glIsEnabled() with argument GL_TEXTURE_COORD_ARRAY
       glGet() with argument GL_TEXTURE_COORD_ARRAY_SIZE
       glGet() with argument GL_TEXTURE_COORD_ARRAY_TYPE
       glGetPointerv() with argument GL_TEXTURE_COORD_ARRAY_POINTER
