◆ SyscallFailed() [1/3]

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

noexcept

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.
exception_type	the classname of the Exception specialization. The default is "SyscallFailed".

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