Name

glGetBufferParameteriv — return parameters of a buffer object

`void glGetBufferParameteriv(`	GLenum `target`,
	GLenum `pname`,
	GLint * `params)`;

target: Specifies the target buffer object. The symbolic constant must be GL_ARRAY_BUFFER or GL_ELEMENT_ARRAY_BUFFER.
pname: Specifies the symbolic name of a buffer object parameter. Accepted values are GL_BUFFER_SIZE or GL_BUFFER_USAGE.
params: Returns the requested parameter.

glGetBufferParameteriv returns in params a selected parameter of the buffer object specified by target.

pname names a specific buffer object parameter, as follows:

GL_BUFFER_SIZE: params returns the size of the buffer object, measured in bytes. The initial value is 0.
GL_BUFFER_USAGE: params returns the buffer object's usage pattern. The initial value is GL_STATIC_DRAW.

If an error is generated, no change is made to the contents of params.

GL_INVALID_ENUM is generated if target or pname is not an accepted value.

GL_INVALID_OPERATION is generated if the reserved buffer object name 0 is bound to target.
