146 * (note, this must be documented a lot more)
147 * ast_add_profile allocates a generic 'counter' with a given name,
148 * which can be shown with the command 'show profile <name>'
150 * The counter accumulates positive or negative values supplied by
151 * ast_add_profile(), dividing them by the 'scale' value passed in the
152 * create call, and also counts the number of 'events'.
153 * Values can also be taked by the TSC counter on ia32 architectures,
154 * in which case you can mark the start of an event calling ast_mark(id, 1)
155 * and then the end of the event with ast_mark(id, 0).
156 * For non-i386 architectures, these two calls return 0.
