Detailed Description

A dynamically loadable module

Typedef Documentation

◆ pw_impl_module_init_func_t

typedef int(* pw_impl_module_init_func_t) (struct pw_impl_module *module, const char *args)

Module init function signature.

Parameters
moduleA Module Impl
argsArguments to the module
Returns
0 on success, < 0 otherwise with an errno style error

A module should provide an init function with this signature. This function will be called when a module is loaded.

Function Documentation

◆ pw_context_load_module()

struct pw_impl_module * pw_context_load_module ( struct pw_context * context,
const char * name,

Load a module.

Parameters
contexta Context
namename of the module to load
argsA string with arguments for the module
