glGenTextures

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.
