NAME
glUniformBlockBinding - assign a binding point to an active uniform
block
C SPECIFICATION
void glUniformBlockBinding(GLuint program, GLuint uniformBlockIndex,
GLuint uniformBlockBinding);
PARAMETERS
program
The name of a program object containing the active uniform block
whose binding to assign.
uniformBlockIndex
The index of the active uniform block within program whose binding
to assign.
uniformBlockBinding
Specifies the binding point to which to bind the uniform block with
index uniformBlockIndex within program.
DESCRIPTION
Binding points for active uniform blocks are assigned using
glUniformBlockBinding. Each of a program's active uniform blocks has a
corresponding uniform buffer binding point. program is the name of a
program object for which the command glLinkProgram() has been issued in
the past.
If successful, glUniformBlockBinding specifies that program will use
the data store of the buffer object bound to the binding point
uniformBlockBinding to extract the values of the uniforms in the
uniform block identified by uniformBlockIndex.
When a program object is linked or re-linked, the uniform buffer object
binding point assigned to each of its active uniform blocks is reset to
zero.
ERRORS
GL_INVALID_VALUE is generated if uniformBlockIndex is not an active
uniform block index of program.
GL_INVALID_VALUE is generated if uniformBlockBinding is greater than or
equal to the value of GL_MAX_UNIFORM_BUFFER_BINDINGS.
GL_INVALID_VALUE is generated program is not the name of a program
object generated by the GL.
NOTES
glUniformBlockBinding is available only if the GL version is 3.1 or
greater.
