NID lookup system.

Function Documentation

module_get_by_name_nid()

int module_get_by_name_nid	(	SceUID	pid,
		const char *	name,
		uint32_t	nid,
		tai_module_info_t *	info
	)

Gets a loaded module by name or NID or both.

If name is NULL, then only the NID is used to locate the loaded module. If name is not NULL then it will be used to lookup the loaded module. If NID is not TAI_IGNORE_MODULE_NID, then it will be used in the lookup too. If name is NULL and NID is TAI_IGNORE_MODULE_NID then if there is only one main module, it will be returned.

Parameters

[in]	pid	The pid
[in]	name	The name to lookup. Can be NULL.
[in]	nid	The nid to lookup. Can be TAI_IGNORE_MODULE_NID.
[out]	info	The information

Returns

Zero on success, < 0 on error

• TAI_ERROR_INVALID_MODULE if both name and NID are undefined and there are multiple main modules. KERNEL_PID will always return this error.

module_get_export_func()

int module_get_export_func	(	SceUID	pid,
		const char *	modname,
		uint32_t	libnid,
		uint32_t	funcnid,
		uintptr_t *	func
	)

Gets an exported function address.

Parameters

[in]	pid	The pid
[in]	modname	The name of module to lookup
[in]	libnid	NID of the exporting library. Can be TAI_ANY_LIBRARY.
[in]	funcnid	NID of the exported function
[out]	func	Output address of the function

Returns

Zero on success, < 0 on error

Definition at line 326 of file module.c.

module_get_import_func()

int module_get_import_func	(	SceUID	pid,
		const char *	modname,
		uint32_t	target_libnid,
		uint32_t	funcnid,
		uintptr_t *	stub
	)

Gets an imported function stub address.

Parameters

[in]	pid	The pid
[in]	modname	The name of the module importing the function
[in]	target_libnid	The target's library NID. Can be TAI_ANY_LIBRARY
[in]	funcnid	The target's function NID
[out]	stub	Output address to stub calling the imported function

Returns

Zero on success, < 0 on error

Definition at line 392 of file module.c.

module_get_offset()

int module_get_offset	(	SceUID	pid,
		SceUID	modid,
		int	segidx,
		size_t	offset,
		uintptr_t *	addr
	)

Gets an offset from a segment in a module.

Parameters

[in]	pid	The pid of caller
[in]	modid	The module to offset from
[in]	segidx	Segment in module to offset from
[in]	offset	Offset from segment
[out]	addr	Output final address

Returns

Zero on success, < 0 on error
