Chapter 7 G glGenTextures glGenTextures glGenTextures: generate texture names. C Specification void glGenTextures( GLsizei n, GLuint *textures) Parameters n textures Specifies the number of texture names to be generated. 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.
