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.
Errors
GL_INVALID_VALUE is generated if n is negative.
