glGenFramebuffers: generate framebuffer object names

Function Definition

 void glGenFramebuffers(GLsizei n​, GLuint *ids​);
Specifies the number of framebuffer object names to generate.
Specifies an array in which the generated framebuffer object names are stored.


glGenFramebuffers returns n​ framebuffer object names in ids​. There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names was in use immediately before the call to glGenFramebuffers.

Framebuffer object names returned by a call to glGenFramebuffers are not returned by subsequent calls, unless they are first deleted with glDeleteFramebuffers.

The names returned in ids​ are marked as used, for the purposes of glGenFramebuffers only, but they acquire state and type only when they are first bound.


GL_INVALID_VALUE is generated if n​ is negative.
