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.


glGenTextures is available only if the GL version is 1.1 or greater.


GL_INVALID_VALUE is generated if n is negative.

GL_INVALID_OPERATION is generated if glGenTextures is executed between the execution of glBegin and the corresponding execution of glEnd.
