Here is a detailed description of the notes

2 Creating a thread function

int Pthread_create (pthread_t *thread, const pthread_attr_t *attr,
void * (*start_routine) (void *), void *arg);

Parameter meaning:

typedef unsigned LONG int pthread_t

(1) pthread_t *thread: storage thread ID Unique

(2) const pthread_attr_t *ATTR: Thread property setting is typically null for stack-related properties

(3) void * (*start_routine) (void *): function pointer specifies which function code to run

(4) void *arg: The parameter address of the running function is usually passed to the parameter of the custom function

Example: Creating a new thread and passing multiple parameters using a struct note that when compiling, add-lpthread

1#include <pthread.h>2#include <stdio.h>3#include <stdlib.h>4#include <string.h>5 6 structStudent7 {8     intAge ;9     Char*name;Ten }; One  A void*print (structStudent *str) - { -printf"The age is %d\n",str->Age ); theprintf"The name is%s\n",str->name); - } -  - intMain () + { -     structstudent Stu; + pthread_t thread_id; AStu.age = -; atStu.name ="GoGoGo"; -Pthread_create (&thread_id,null, (void*) *print,&stu);//Creating Threads -printf"The new thread ID is%u\n", thread_id); -Pthread_join (Thread_id,null);//wait for the child thread to end in the main thread -     return 1; -}

Added: int pthread_join (pthread_t thread, void **retval), thread wait function
