glGetVertexAttribPointerv: return the address of the specified generic vertex attribute pointer

Function Definition

 void glGetVertexAttribPointerv(GLuint index​, GLenum pname​, GLvoid **pointer​);
index
Specifies the generic vertex attribute parameter to be returned.
pname
Specifies the symbolic name of the generic vertex attribute parameter to be returned. Must be GL_VERTEX_ATTRIB_ARRAY_POINTER​.
pointer
Returns the pointer value.

Description

glGetVertexAttribPointerv returns pointer information. index​ is the generic vertex attribute to be queried, pname​ is a symbolic constant indicating the pointer to be returned, and params​ is a pointer to a location in which to place the returned data.

The pointer​ returned is a byte offset into the data store of the buffer object that was bound to the GL_ARRAY_BUFFER​ target (see glBindBuffer) when the desired pointer was previously specified.

Notes

The state returned is retrieved from the currently bound vertex array object.

The initial value for each pointer is 0.

Errors

GL_INVALID_OPERATION​ is generated if no vertex array object is currently bound.

GL_INVALID_VALUE​ is generated if index​ is greater than or equal to GL_MAX_VERTEX_ATTRIBS​.

GL_INVALID_ENUM​ is generated if pname​ is not an accepted value.

Associated Gets

glGet with argument GL_MAX_VERTEX_ATTRIBS​
