glGenTextures: generate texture names
Function Definition
void glGenTextures(GLsizei n, GLuint * textures);
- 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.
Associated Gets
