◆ 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
descriptiona description of the problem.
source_filethe file name where the problem occured.
linethe line number where the exception occured.
syscallthe name of the syscall that failed.
errthe error returned by the failed syscall.
class_descthe ClassDesc for the object causing the exception.
exception_typethe 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.
