glDeleteBuffers — delete named buffer objects
void glDeleteBuffers( | GLsizei n, |
const GLuint * buffers); |
n Specifies the number of buffer objects to be deleted.
buffers Specifies an array of buffer objects to be deleted.
glDeleteBuffers deletes n buffer objects named by the elements of the array buffers. After a buffer object is deleted, it has no contents, and its name is free for reuse (for example by glGenBuffers). If a buffer object that is currently bound is deleted, the binding reverts to 0 (the absence of any buffer object).
glDeleteBuffers silently ignores 0's and names that do not correspond to existing buffer objects.
GL_INVALID_VALUE is generated if n is negative.
