NAME

       glInvalidateBufferData - invalidate the content of a buffer object's data store

C SPECIFICATION

       void glInvalidateBufferData(GLuint buffer);

PARAMETERS

       buffer
	   The name of a buffer object whose data store to invalidate.

DESCRIPTION

       glInvalidateBufferData invalidates all of the content of the data store of a buffer object. After invalidation, the content of the buffer's
       data store becomes undefined.

ERRORS

       GL_INVALID_VALUE is generated if buffer is not the name of an existing buffer object.

       GL_INVALID_OPERATION is generated if any part of buffer is currently mapped.

ASSOCIATED GETS

       glGetBufferParameter() with argument GL_BUFFER_SIZE

NAME

       glClearBufferData - fill a buffer object's data store with a fixed value

C SPECIFICATION

       void glClearBufferData(GLenum target, GLenum internalformat, GLenum format, GLenum type, const void * data);

PARAMETERS

       target
	   Specify the target of the operation.  target must be one of the global buffer binding targets.

       internalformat
	   The internal format with which the data will be stored in the buffer object.

       size
	   The size, in basic machine units of the range of the data store to fill.

       format
	   The format of the data in memory addressed by data.

       type
	   The type of the data in memory addressed by data.

       data
	   The address of a memory location storing the data to be replicated into the buffer's data store.

DESCRIPTION

       glClearBufferData fills the entirety of a buffer object's data store with data from client memory. Data, initially supplied in a format
       specified by format in data type type is read from the memory address given by data and converted into the internal representation given by
       internalforamt. This converted data is then replicated throughout the buffer object's data store.

       If data is NULL, then the buffer's data store is filled with zeros.

ERRORS

       GL_INVALID_ENUM is generated if target not one of the generic buffer binding targets.

       GL_INVALID_VALUE is generated if no buffer is bound to target.

       GL_INVALID_ENUM is generated if internalformat is not a sized internal format.

       GL_INVALID_OPERATION is generated if any part of the buffer's data store is mapped with glMapBufferRange() or glMapBuffer.()

SEE ALSO

       glClearBufferSubData().
