glBindBufferBase: bind a buffer object to an indexed buffer target
Function Definition
void glBindBufferBase(GLenum target, GLuint index, GLuint buffer);
- target
- Specifies the target buffer object. The symbolic constant must be GL_ATOMIC_COUNTER_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER, GL_UNIFORM_BUFFER or GL_SHADER_STORAGE_BUFFER.
- index
- Specify the index of the binding point within the array specified by target.
- buffer
- The name of a buffer object to bind to the specified binding point.
Description
glBindBufferBase binds the buffer object buffer to the binding point at index index of the array of targets specified by target. Each target represents an indexed array of buffer binding points, as well as a single general binding point that can be used by other buffer manipulation functions such as glBindBuffer or glMapBuffer. In addition to binding buffer to the indexed buffer binding target, glBindBufferBase also binds buffer to the generic buffer binding point specified by target.
Notes
Calling glBindBufferBase is equivalent to calling glBindBufferRange with offset zero and size equal to the size of the buffer.
The GL_ATOMIC_COUNTER_BUFFER target is available only if the GL version is 4.2 or greater.
The GL_SHADER_STORAGE_BUFFER target is available only if the GL version is 4.3 or greater.
Errors
GL_INVALID_ENUM is generated if target is not GL_ATOMIC_COUNTER_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER, GL_UNIFORM_BUFFER or GL_SHADER_STORAGE_BUFFER.
GL_INVALID_VALUE is generated if index is greater than or equal to the number of target-specific indexed binding points.
GL_INVALID_VALUE is generated if buffer does not have an associated data store, or if the size of that store is zero.
