linux下syscall函数（pid,tid）

NAME

syscall-间接系统调⽤

SYNOPSIS

#define_GNU_SOURCE

#include

#include/*ForSYS_xxxdefinitions*/

intsyscall(intnumber,...);

DESCRIPTION

syscall()执⾏⼀个系统调⽤，根据指定的参数number和所有系统调⽤的汇编语⾔接⼝来确定调⽤哪个系统调⽤。

系统调⽤所使⽤的符号常量可以在头⽂件⾥⾯找到。

/***************************************************************************************************************************************************/

Linux中，每个进程有⼀个pid，类型pid_t，由getpid()取得。Linux下的POSIX线程也有⼀个id，类型pthread_t，由pthread_self()

取得，该id由线程库维护，其id空间是各个进程独⽴的（即不同进程中的线程可能有相同的id）。Linux中的POSIX线程库实现的线程其实

也是⼀个进程（LWP），只是该进程与主进程（启动线程的进程）共享⼀些资源⽽已，⽐如代码段，数据段等。

有时候我们可能需要知道线程的真实pid。⽐如进程P1要向另外⼀个进程P2中的某个线程发送信号时，既不能使⽤P2的pid，更不能使⽤线

程的pthreadid，⽽只能使⽤该线程的真实pid，称为tid。

有⼀个函数gettid()可以得到tid，但glibc并没有实现该函数，只能通过Linux的系统调⽤syscall来获取。

测试实例：

#include

#include

#include

#include

#include

#include

int

main(intargc,char*argv[])

{

pid_ttid;

tid=syscall(SYS_gettid);

printf("tid:%dn",tid);

tid=syscall(SYS_tgkill,getpid(),tid,SIGHUP);

printf("tid:%d...n",tid);

}
