man glBindBufferBase (3): bind a buffer object to an indexed buffer target

C SPECIFICATION

void glBindBufferBase(GLenum target, GLuint index, GLuint buffer);

PARAMETERS

target

: Specify the target of the bind operation. target must be one of GL_ATOMIC_COUNTER_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER or GL_UNIFORM_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.

ERRORS

GL_INVALID_ENUM is generated if target is not GL_ATOMIC_COUNTER_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER or GL_UNIFORM_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.
