Field Documentation

◆ buildopt_sum

const char buildopt_sum[33]

The value of AST_BUILDOPT_SUM when this module was compiled

Definition at line 363 of file module.h.

Referenced by inspect_module().

◆ description

const char* description

◆ enhances

const char* enhances

Modules that we provide enhanced functionality for.

This is similar to a "requires" but specifies that we add functionality to the other modules. Any module that requires something we "enhances" will also require us, but only if we are dlopen'ed.

Example:

  • res_fax_spandsp has .enhances = "res_fax".
  • res_my_module has .requires = "res_fax" but has no direct knowledge of res_fax_spandsp.

This forces the following startup order among the 3 modules: 1) res_fax starts. 2) res_fax_spandsp starts, holds a reference to res_fax. 3) res_mymod starts, holds a reference to res_fax and res_fax_spandsp.

If res_fax_spandsp were not being loaded res_mymod would load with res_fax only. If res_fax_spandsp were later loaded res_mymod would get a reference to it.

◆ flags

unsigned int flags

Definition at line 360 of file module.h.

◆ key

const char* key

This holds the ASTERISK_GPL_KEY, signifiying that you agree to the terms of the Asterisk license as stated in the ASTERISK_GPL_KEY. Your module will not load if it does not return the EXACT key string.

Definition at line 359 of file module.h.

◆ load

enum ast_module_load_result(* load) (void)

Register stuff etc. Optional.

Definition at line 344 of file module.h.

Referenced by ApiDeclaration::load_file(), ResourceListing::load_file(), and start_resource().

◆ load_pri

unsigned char load_pri

This value represents the order in which a module's load() function is initialized. The lower this value, the higher the priority. The value is only checked if the AST_MODFLAG_LOAD_ORDER flag is set. If the AST_MODFLAG_LOAD_ORDER flag is not set, this value will never be read and the module will be given the lowest possible priority on load.

Definition at line 370 of file module.h.

Referenced by module_vector_cmp(), and start_resource_attempt().

◆ name

const char* name

◆ optional_modules

const char* optional_modules

Comma-separated list of optionally required modules.

The listed modules are optional, but load order is enforced. For example app_voicemail optionally requires res_adsi. This means that app_voicemail will happily load without res_adsi, but if both are being loaded the module loader will force res_adsi to start first.

Referenced by module_post_register().

◆ reload

int(* reload) (void)

Config etc. Optional.

Definition at line 346 of file module.h.

Referenced by ast_module_reload(), and module_matches_helper_type().

◆ requires

const char* requires

Modules which must always be started first, in comma-separated string format.

Definition at line 373 of file module.h.

◆ reserved1

void* reserved1

These reserved fields should be NULL, they exist to allow addition to this structure in a non-breaking way.

◆ reserved2

void* reserved2

Definition at line 411 of file module.h.

◆ reserved3

void* reserved3

Definition at line 412 of file module.h.

◆ reserved4

void* reserved4

Definition at line 413 of file module.h.

◆ self

struct ast_module* self

◆ support_level

enum ast_module_support_level support_level

The support level for the given module
