据我了解，C语言没有此功能，但在gdb中使用了： https://fossies.org/linux/gdb/gdb/gdbserver/linux-low.c第1534行
TRY
/* Flush any pending changes to the process's registers. */
{
regcache_invalidate_thread (thread);
/* Finally, let it resume. */
if (the_low_target.prepare_to_resume != NULL)
the_low_target.prepare_to_resume (lwp);
}
CATCH (ex, RETURN_MASK_ERROR)
{
if (!check_ptrace_stopped_lwp_gone (lwp))
throw_exception (ex);
}
END_CATCH
请说明这怎么可能？
谢谢

不，C没有例外。
Somewhere inside the gdbserver code被定义为SELECT
pm.ProjectCode AS ProjectCode,
bl.PartNum AS PartNum,
SUM(pm.Quantity * bl.TotalQty) AS BOMItemCount,
SUM(
CASE WHEN blh.ParentPartNum = bl.PartNum
THEN pm.Quantity * bl.TotalQty
ELSE 0
END
) AS NextBOMItemCount,
bl.mp AS mp,
p.complete AS complete,
bl.RMInd AS RMInd,
bl.M_PartNum AS M_PartNum
FROM
projectmachine AS pm
INNER JOIN projectbomlist AS bl
ON pm.MachineListID = bl.MachineListID
AND pm.ProjectCode = bl.ProjectCode
INNER JOIN join projects AS p
ON pm.ProjectCode = p.ProjectCode
AND p.AfterProjectHeirarchyInd = 'Y'
INNER JOIN projectbomlistheirarchy blh
ON bl.ProjectCode = blh.ProjectCode
WHERE
pm.ProjectCode = 'AB212323'
GROUP BY
pm.ProjectCode,
bl.PartNum,
bl.mp,
p.complete,
bl.RMInd,
bl.M_PartNum
ORDER BY
pm.ProjectCode,
bl.PartNum
，TRY和CATCH为模拟异常的宏。

快速浏览链接后，我可以观察到std :: vector，std :: move，...
似乎代码包含c ++。
