◆ _SifLoadModule()

int _SifLoadModule	(	const char *	path,
		int	arg_len,
		const char *	args,
		int *	modres,
		int	fno,
		int	dontwait )

extern

Low-level function for loading and executing an IRX module.

Parameters

path	Path to an IRX module
arg_len	Length, in bytes, of the argument list
args	List of arguments to pass to the IRX on startup
*modres	Pointer to a variable that will store the return value from the IRX's _start() function
fno	Function number of function to execute.
dontwait	Whether to wait for the module's _start function to finish executing.

Returns: The ID of the loaded module on success, or an error if the module couldn't be loaded.

Unless required, use the higher-level functions instead.

◆ SifExecModuleBuffer()

int SifExecModuleBuffer	(	void *	ptr,
		u32	size,
		u32	arg_len,
		const char *	args,
		int *	mod_res )

extern

Transfer an IRX module from EE RAM to IOP RAM and execute it.

Parameters

ptr	Pointer to a buffer in EE RAM where the IRX module will be loaded from
size	Size of the buffer in EE RAM that contains the IRX module
arg_len	Length, in bytes, of the argument list
args	List of arguments to pass to the IRX on startup
mod_res	Pointer to a variable that will store the return value from the IRX's _start() function

Returns: The ID of the loaded module on success, or an error if the module couldn't be loaded.

Transfers an IRX module stored in a buffer in EE RAM to the IOP, and calls SifLoadModuleBuffer to load and execute the module. See SifLoadModule for details on the arg_len and args parameters. If mod_res is non-NULL, the result code from the module's _start() function is stored here.

◆ SifExecModuleFile()

int SifExecModuleFile	(	const char *	path,
		u32	arg_len,
		const char *	args,
		int *	mod_res )

extern

Read an IRX module from a file into IOP RAM and execute it.

Parameters

path	Path to an IRX module
arg_len	Length, in bytes, of the argument list
args	List of arguments to pass to the IRX on startup
mod_res	Pointer to a variable that will store the return value from the IRX's _start() function

Returns: The ID of the loaded module on success, or an error if the module couldn't be loaded.

Loads an IRX module from the specified path into a buffer on the IOP, then calls SifLoadModuleBuffer to load and execute the module. See SifLoadModule for details on the arg_len and args parameters. This function is useful if you need to load an IRX module from a prohibited device, such as the memory card.

◆ SifIopGetVal()

int SifIopGetVal	(	u32	iop_addr,
		void *	val,
		int	type )

extern

Read a value from an address within the IOP's memory space.

Parameters

iop_addr	Address within the IOP's address space to read from
val	Pointer to a variable that stores the value read
type	A type describing the size of the data to read

Returns: 0 on success, or an error code if an error occurred.

Reads data of the size specified by type from the IOP address specified by iop_addr. Use the following types to specify the size of the data to read:

::LF_VAL_BYTE to write an 8-bit value
::LF_VAL_SHORT to write a 16-bit value
::LF_VAL_LONG to write a 32-bit value

Note: Because iop_addr can be any address within the IOP's address space, it's possible to read from IOP hardware registers. However, in most cases the EE can read the IOP's hardware registers directly so there is little use for this function.

Definition at line 246 of file loadfile.c.

◆ SifIopSetVal()

int SifIopSetVal	(	u32	iop_addr,
		int	val,
		int	type )

extern

Write a value to an address within the IOP's memory space.

Parameters

iop_addr	Address to modify in the IOP's address space
val	Data to write at iop_addr
type	A type describing the size of the val argument

Returns: Previous value at iop_addr on success (?), or an error code if an error occurred.

Writes the data passed in val to the IOP address specified by iop_addr. Use the following types specify the size of data write:

::LF_VAL_BYTE to write an 8-bit value
::LF_VAL_SHORT to write a 16-bit value
::LF_VAL_LONG to write a 32-bit value

Note: Because iop_addr can be any address within the IOP's address space, it's possible to modify IOP hardware registers. However, in most cases the EE can modify the IOP's hardware registers directly so there is little use for this function.

◆ SifLoadElf()

int SifLoadElf	(	const char *	path,
		t_ExecData *	data )

Load an ELF executable into EE RAM.

Parameters

path	Path to an ELF executable
data	Pointer to a variable that will store information about the loaded executable

Returns: 0 on success, or an error code if an error occurred.

Loads the ELF executable specified by path into EE RAM. data points to a t_ExecData structure where information about the loaded executable will be returned.

Warning: It's possible to overwrite your program if the ELF that you're trying to load overlaps your program's memory space. Always ensure that the target ELF will load before or after your program's code and data addresses.

◆ SifLoadElfEncrypted()

int SifLoadElfEncrypted	(	const char *	path,
		t_ExecData *	data )

extern

Load a MagicGate-encrypted ELF executable into EE RAM.

Parameters

path	Path to an ELF executable
data	Pointer to a variable that will store information about the loaded executable

Returns: 0 on success, or an error code if an error occurred.

There is no real use for this function; it is only included in ps2lib for completeness.

Definition at line 209 of file loadfile.c.

◆ SifLoadElfPart()

int SifLoadElfPart	(	const char *	path,
		const char *	secname,
		t_ExecData *	data )

extern

Load the specified section of an ELF executable into EE RAM.

Parameters

path	Path to an ELF executable
secname	The name of a single section to load from the ELF, or "all" to load all sections
data	Pointer to a variable that will store information about the loaded executable

Returns: 0 on success, or an error code if an error occurred.

Loads the section secname from the ELF file specified by path into EE RAM.

data points to a t_ExecData structure where information about the loaded section will be returned.

Warning: Don't ever use this function, it does not work as intended.

Deinitializes the LOADFILE library in preparation of an IOP reset.

Definition at line 59 of file loadfile.c.

◆ SifLoadFileInit()

int SifLoadFileInit ( void )

extern

Returns: 0 on success, E_SIF_RPC_BIND if unable to connect to the server.

Initializes the LOADFILE API and binds to the remote LOADFILE RPC server.

◆ SifLoadModule()

int SifLoadModule	(	const char *	path,
		int	arg_len,
		const char *	args )

extern

Load and execute an IRX module.

Parameters

path	Path to an IRX module
arg_len	Length, in bytes, of the argument list
args	List of arguments to pass to the IRX on startup

Returns: The ID of the loaded module on success, or an error if the module couldn't be loaded.

Loads an IRX module from the specified path, and executes it. The args parameter specifies a list of arguments that are passed to the loaded module as the argv[] array. Each argument string in args must be seperated by NUL ('\0'). Pass the length of the entire args list, including the NUL seperators in the args_len parameter.

Note: By default, modules cannot be loaded directly from the memory card. If you need to load modules from the memory card, you should use SifExecModuleFile or link with the sbv-lite library (http://www.0xd6.org).
