Name

glGenTextures — generate texture names

C Specification

void glGenTextures(GLsizei n,
 GLuint * textures);
 

Parameters

n

Specifies the number of texture names to be generated.

textures

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

Description

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.

Notes

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

Errors

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.

Associated Gets

glIsTexture
