glDrawElements Function

GL_APICALL void GL_APIENTRY glDrawElements(
     GLenum mode,
     GLsizei count,
     GLenum type,
     const void * indices
);

	Name	Description
in	mode	Primitive mode
in	count	Amount of vertex data to render
in	type	Data type for the vertex indices
in	indices	Pointer to a vertex index, or offset to the region to start using within the vertex indices

No values are returned.

Uses vertex indices to render primitives.

Uses a vertex index array to access an array of vertex data. Set mode to one of the following values when the geometry shader is not in use.

GL_TRIANGLES	Triangles
GL_TRIANGLE_STRIP	Triangle strip
GL_TRIANGLE_FAN	Triangle fan

Specify a value of GL_GEOMETRY_PRIMITIVE_DMP when the geometry shader is in use.

Set type to the type of the vertex index array. Specify a value of GL_UNSIGNED_BYTE or GL_UNSIGNED_SHORT.

When vertex buffer objects are not in use, set indices with a pointer to the vertex indices. When vertex buffer objects are in use, set indices with the offset to the region to start using within the vertex indices.

This function generates the following errors.

GL_INVALID_ENUM	The mode or type argument was set to an invalid value.
GL_INVALID_FRAMEBUFFER_OPERATION	The framebuffer was configured incorrectly.
GL_INVALID_OPERATION	This function was called without any command-list objects bound.
GL_INVALID_OPERATION	The mode argument was either set to GL_GEOMETRY_PRIMITIVE_DMP when a geometry shader had not been linked to the current program, or it was set to a value other than GL_GEOMETRY_PRIMITIVE_DMP when a geometry shader had been linked to the current program.
