Detailed Description

This is thrown when an system call fails with an errno.

Constructor & Destructor Documentation

SyscallFailed()

sc::SyscallFailed::SyscallFailed	(	const char *	description = 0,
		const char *	source_file = 0,
		int	line = 0,
		const char *	syscall = 0,
		int	err = 0,
		const ClassDesc *	class_desc = 0,
		const char *	exception_type = "SyscallFailed"
	)

Create a SyscallFailed exception.

Parameters

description	a description of the problem.
source_file	the file name where the problem occured.
line	the line number where the exception occured.
syscall	the name of the syscall that failed.
err	the error returned by the failed syscall.
class_desc	the ClassDesc for the object causing the exception.
exception_type	the classname of the SCException specialization. The default is "SyscallFailed".

It is suggested that the special macros FILE and LINE be given as the file and line arguments, respectively.

Member Function Documentation

syscall()

const char* sc::SyscallFailed::syscall ( ) const

inline

Returns the file name of the file that caused the error, if known.

Otherwise 0 is returned.
