I have used fork() in C to start another process. How do I start a new thread?

Since you mentioned fork() I assume you're on a Unix-like system, in which case POSIX threads (usually referred to as pthreads) are what you want to use.
由于您提到了fork()，所以我假设您是在一个类unix系统上，在这种情况下，您希望使用POSIX线程(通常称为pthreads)。
Specifically, pthread_create() is the function you need to create a new thread. Its arguments are:
具体地说，pthread_create()是创建新线程所需的函数。它的参数是:
int pthread_create(pthread_t * thread, pthread_attr_t * attr, void *
(*start_routine)(void *), void * arg);
The first argument is the returned pointer to the thread id. The second argument is the thread arguments, which can be NULL unless you want to start the thread with a specific priority. The third argument is the function executed by the thread. The fourth argument is the single argument passed to the thread function when it is executed.
第一个参数是指向线程id的返回指针，第二个参数是线程参数，它可以是空的，除非您想以特定的优先级启动线程。第三个参数是线程执行的函数。第四个参数是线程函数执行时传递给它的单个参数。

AFAIK, ANSI C doesn't define threading, but there are various libraries available.
AFAIK, ANSI C没有定义线程，但是有各种可用的库。
If you are running on Windows, link to msvcrt and use _beginthread or _beginthreadex.
如果您在Windows上运行，请链接到msvcrt并使用_beginthread或_beginthreadex。
If you are running on other platforms, check out the pthreads library (I'm sure there are others as well).
如果您正在其他平台上运行，请查看pthreads库(我肯定还有其他平台)。

Threads are not part of the C standard, so the only way to use threads is to use some library (eg: POSIX threads in Unix/Linux, _beginthread/_beginthreadex if you want to use the C-runtime from that thread or just CreateThread Win32 API)
线程不是C标准的一部分，所以使用线程的唯一方法是使用一些库(例如:Unix/Linux中的POSIX线程，如果您希望使用该线程的C-runtime或CreateThread Win32 API)
