glGenTextures — generate texture names

C Specification

void glGenTextures(GLsizei n, GLuint * textures);



Specifies the number of texture names to be generated.


Specifies an array in which the generated texture names are stored.


glGenTextures returns n texture names in textures. 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 glGenTextures.

The generated textures have no dimensionality; they assume the dimensionality of the texture target to which they are first bound (see glBindTexture()).

Texture names returned by a call to glGenTextures are not returned by subsequent calls, unless they are first deleted with glDeleteTextures().


GL_INVALID_VALUE is generated if n is negative.
