glGenTextures

generate texture names

Signature

glGenTextures( GLsizei ( n ) , GLuint * ( textures ) )-> void
glGenTextures( n , textures )

Parameters

VariablesDescription
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 .

Errors

GL_INVALID_VALUE is generated if n is negative.
