78 * This function reloads the specified module, or if no modules are specified,
79 * it will reload all loaded modules.
81 * \note Modules are reloaded using their reload() functions, not unloading
82 * them and loading them again.
84 * \return Zero if the specified module was not found, 1 if the module was
85 * found but cannot be reloaded, -1 if a reload operation is already in
86 * progress, and 2 if the specfied module was found and reloaded.

134 * to registered with the Asterisk core (and unregistered) at the appropriate

144 * CVS from modifying them in this file; under normal circumstances they would
145 * not be present and CVS would expand the Revision keyword into the file's

178 * \brief support for event profiling
180 * (note, this must be documented a lot more)
181 * ast_add_profile allocates a generic 'counter' with a given name,
182 * which can be shown with the command 'show profile <name>'
184 * The counter accumulates positive or negative values supplied by
185 * ast_add_profile(), dividing them by the 'scale' value passed in the
186 * create call, and also counts the number of 'events'.
187 * Values can also be taked by the TSC counter on ia32 architectures,
188 * in which case you can mark the start of an event calling ast_mark(id, 1)
189 * and then the end of the event with ast_mark(id, 0).
190 * For non-i386 architectures, these two calls return 0.
