如下是一个动态图的源码，请问如何在中间插入一段文字

Question

#include <stdio.h>

#include <math.h>
#include <windows.h>
#include <tchar.h>
float f(float x, float y, float z) {
float a = x * x + 9.0f / 4.0f * y * y + z * z - 1;

}

if (f(x, y, z) <= 0.0f)

}

else

}
}

for (sy = 0; sy < 25; sy++) {
COORD coord = { 0, sy };

WriteConsole(o, buffer[sy], 79, NULL, 0);
}

Answer 1

函数原型：Int pthread_mutex_init(pthread_mutex_t *restrict_mutex,const pthread_mutextattr_t *restrict attr)该函数主要用于多线程中互斥锁的初始化。如果attr为空的话，则是默认属性，而默认属性的快速互斥锁。pthread_mutex_init完成成功后会返回0，其他值都是错误的。int pthread_mutextattr_destroy(pthread_mutextattr_t *restrict_mutext)该函数是销毁线程互斥锁设定互斥锁的作用域：Int pthread_mutextattr_setpshared(pthread_mutexattr_t *restrict mutext, int pshared)在多线程中是共享互斥锁的。如果想在多个进程中共享互斥锁，可以把pshared设置PTHREAD_PROCESS_SHARED如果只想在有同属于一个进程创建的线程中共享互斥锁，则可以把pshared设置为PTHREAD_PROCESS_PRIVATE获得互斥锁的作用域：int pthread_mutexattr_getpshared(pthread_mutexattr_t *restrict mutext,int *pshared);设定互斥锁类型的属性：int pthread_mutexattr_settype(pthread_mutexattr_t *restrict mutext,int type)其中type类型都有：PTHREAD_MUTEX_NOMRAL：此类型的互斥锁不会检测死锁而其中的缺省值值是PTHREAD_MUTEX_DEFAULTPTHREAD_MUTEX_ERRORCHECK:是提供错误检查int pthread_mutexattr_setprotocal(pthread_mutexattr_t *attr,int protocal)protocal可以设置互斥锁属性的协议PTHREAD_PRIO_NONEPTHREAD_PRIO_INHERITPTHREAD_PRIO_PROTECT
