Functions and values

Function or value	Description
`functionArgRegister arg1 arg2 arg3` Full Usage: `functionArgRegister arg1 arg2 arg3` Parameters: arg0 : `BinHandle` arg1 : `OS` arg2 : `int` Returns: `RegisterID`	Obtain the register ID used for the nth function call parameter. Since actual calling convention may vary depending on the binaries, this function only returns a generally used register for the given architecture and the file format. arg0 : `BinHandle` arg1 : `OS` arg2 : `int` Returns: `RegisterID`
`isNonVolatile arg1 arg2 arg3` Full Usage: `isNonVolatile arg1 arg2 arg3` Parameters: arg0 : `BinHandle` arg1 : `OS` arg2 : `RegisterID` Returns: `bool`	Check if the given register is non-volatile register in the given binary. Non-volatile registers are preserved by callee, i.e., callee-saved registers. arg0 : `BinHandle` arg1 : `OS` arg2 : `RegisterID` Returns: `bool`
`returnRegister arg1` Full Usage: `returnRegister arg1` Parameters: arg0 : `BinHandle` Returns: `RegisterID`	Obtain the register ID used for storing syscall return values. arg0 : `BinHandle` Returns: `RegisterID`
`syscallArgRegister arg1 arg2 arg3` Full Usage: `syscallArgRegister arg1 arg2 arg3` Parameters: arg0 : `BinHandle` arg1 : `OS` arg2 : `int` Returns: `RegisterID`	Obtain the register ID used for the nth syscall parameter. arg0 : `BinHandle` arg1 : `OS` arg2 : `int` Returns: `RegisterID`
`syscallNumRegister arg1` Full Usage: `syscallNumRegister arg1` Parameters: arg0 : `BinHandle` Returns: `RegisterID`	Obtain the register ID used for storing a syscall number. arg0 : `BinHandle` Returns: `RegisterID`
`volatileRegisters arg1` Full Usage: `volatileRegisters arg1` Parameters: arg0 : `BinHandle` Returns: `RegisterID list`	Obtain the list of volatile register IDs arg0 : `BinHandle` Returns: `RegisterID list`
