Name

glBindBufferRange — bind a range within a buffer object to an indexed buffer target

C Specification

void fsfuncglBindBufferRange(GLenumtarget,
 GLuintindex,
 GLuintbuffer,
 GLintptroffset,
 GLsizeiptrsize);
 

Parameters

target

Specify the target of the bind operation. target must be either 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.

offset

The starting offset in basic machine units into the buffer object buffer.

size

The amount of data in machine units that can be read from the buffet object while used as an indexed target.

Description

glBindBufferRange binds a range of the buffer object buffer represented by offset and size 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 glMapBufferRange. In addition to binding a range of buffer to the indexed buffer binding target, glBindBufferBase also binds the range to the generic buffer binding point specified by target.

offset specifies the offset in basic machine units into the buffer object buffer and size specifies the amount of data that can be read from the buffer object while used as an indexed target.

Errors

GL_INVALID_ENUM is generated if target is not GL_TRANSFORM_FEEDBACK_BUFFER or GL_UNIFORM_BUFFER.

GL_INVALID_VALUE is generated if target is GL_TRANSFORM_FEEDBACK_BUFFER andindex is greater than or equal to GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS.

GL_INVALID_VALUE is generated if target is GL_UNIFORM_BUFFER andindex is greater than or equal to GL_MAX_UNIFORM_BUFFER_BINDINGS.

GL_INVALID_VALUE is generated if buffer is not zero and size is less than or equal to zero.

GL_INVALID_VALUE is generated if target is GL_TRANSFORM_FEEDBACK_BUFFER and size or offset are not multiples of 4.

GL_INVALID_VALUE is generated if target is GL_UNIFORM_BUFFER and offset is not a multiple of GL_UNIFORM_BUFFER_OFFSET_ALIGNMENT.

Associated Gets

glGet with argument GL_MAX_UNIFORM_BUFFER_BINDINGS, GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS, or GL_UNIFORM_BUFFER_OFFSET_ALIGNMENT.
