我试图呼吁利用在线集会进行玩具-unlink。
int sys_unlink(const char *filename) {
int ret;
__asm__("int $0x80" : "=a"(ret) : "a"(10), "b"(filename));
return ret;
}
但它并不奏效,它总是回到14岁。
我愿知道,这部法典是否正确,因为我不知道有多少组装。

该法典仅适用于X86(32轨)程序,它没有使用正确的机号进行X86-64程序。 使用<代码>NR_unlink,asm/unistd.h
而不是硬编码<代码>10:
#include <asm/unistd.h>
int sys_unlink(const char *filename)
{
int ret;
asm("int $0x80" : "=a"(ret) : "a"(__NR_unlink), "b"(filename));
return ret;
}
如果您are <>/em>汇编了32个轨道过程,则-14
为EFAULT
,表明在你通过档案名称方面存在问题。 你们怎么说?
我认为,你甚至可以把这项工作局限于一个排在含水层以下的平台: 采用现代方式进行生物勘探,是用油轮提供的 st,通过DVDSO进行连接。 即便是你与不知道(谁知道)系统称之为公约——它只是从DVDSO中引来。 它通过在<条码>environ<> 代码/代码>后隐藏的磁性参数查阅DVDSO,然后将其与其他任何动态图书馆处理。 核心小组根据万国邮联的能力选择系统称为公约。
我知道(因为我试图这样做!) 它难以接触这些DVDSO符号。 glibc不向您出口(或向它们出口任何有用的产品)。 我所看到的唯一可行方式是检查你自己的<代码>/proc/ Self/maps,以便找到DVDSO,然后使用<代码>dl的功能(重复一些校准工作)。
