glGenVertexArrays: generate vertex array object names
Function Definition
void glGenVertexArrays(GLsizei n, GLuint *arrays);
- n
- Specifies the number of vertex array object names to generate.
- arrays
- Specifies an array in which the generated vertex array object names are stored.
Description
glGenVertexArrays returns n vertex array object names in arrays. 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 glGenVertexArrays.
Vertex array object names returned by a call to glGenVertexArrays are not returned by subsequent calls, unless they are first deleted with glDeleteVertexArrays.
The names returned in arrays are marked as used, for the purposes of glGenVertexArrays only, but they acquire state and type only when they are first bound.
Errors
GL_INVALID_VALUE is generated if n is negative.
