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,
const char *  args,
struct pw_properties properties 
)

Load a module.

Parameters
contexta Context
namename of the module to load
argsA string with arguments for the module
propertiesextra global properties
Returns
A Module Impl if the module could be loaded, or NULL on failure.
Examples
export-spa-device.c, export-spa.c, and local-v4l2.c.
