GLGETVERTEXATTRIBPOI(3G)

NAME
glGetVertexAttribPointerv - return the address of the specified generic vertex attribute pointer

C SPECIFICATION

void glGetVertexAttribPointerv(GLuint index, GLenum pname, GLvoid **pointer);

PARAMETERS

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.

If a non-zero named buffer object was bound to the GL_ARRAY_BUFFER target (see glBindBuffer()) when the desired pointer was previously specified, the pointer returned is a byte offset into the buffer object's data store.

NOTES

glGetVertexAttribPointerv is available only if the GL version is 2.0 or greater.

The pointer returned is client-side state.

The initial value for each pointer is 0.

ERRORS

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
