glGenXxxGLsizei
glGenXxxGLsizei is a naming convention used in the OpenGL API for functions that generate one or more object names. The "Xxx" part of the name represents the type of object being generated, such as "Textures" for texture objects, "Buffers" for buffer objects, or "Queries" for query objects. The "GLsizei" suffix indicates that the function takes a GLsizei argument, which is an unsigned integer type used to specify sizes and counts in OpenGL.
These functions are typically used to obtain unique identifiers for OpenGL resources. For example, glGenTextures generates
The typical usage pattern involves calling the function with a count and a pointer to an array
It is important to note that the generated names are not guaranteed to be contiguous or sequential.
