NAME
glDeleteTransformFeedbacks - delete transform feedback objects C SPECIFICATION
void glDeleteTransformFeedbacks(GLsizei n, const GLuint *ids); PARAMETERS
n Specifies the number of transform feedback objects to delete. ids Specifies an array of names of transform feedback objects to delete. DESCRIPTION
glDeleteTransformFeedbacks deletes the n transform feedback objects whose names are stored in the array ids. Unused names in ids are ignored, as is the name zero. After a transform feedback object is deleted, its name is again unused and it has no contents. If an active transform feedback object is deleted, its name immediately becomes unused, but the underlying object is not deleted until it is no longer active. ASSOCIATED GETS
