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;return a * a * a - x * x * z * z * z - 9.0f / 80.0f * y * y * z * z * z;}float h(float x, float z) {for (float y = 1.0f; y >= 0.0f; y -= 0.001f)if (f(x, y, z) <= 0.0f)return y;return 0.0f;}int main() {HANDLE o = GetStdHandle(STD_OUTPUT_HANDLE);_TCHAR buffer[25][80] = { _T(' ') };_TCHAR ramp[] = _T(".:-=+*#%@");for (float t = 0.0f;; t += 0.1f) {int sy = 0;float s = sinf(t);float a = s * s * s * s * 0.2f;for (float z = 1.3f; z > -1.2f; z -= 0.1f) {_TCHAR* p = &buffer[sy++][0];float tz = z * (1.2f - a);for (float x = -1.5f; x < 1.5f; x += 0.05f) {float tx = x * (1.2f + a);float v = f(tx, 0.0f, tz);if (v <= 0.0f) {float y0 = h(tx, tz);float ny = 0.01f;float nx = h(tx + ny, tz) - y0;float nz = h(tx, tz + ny) - y0;float nd = 1.0f / sqrtf(nx * nx + ny * ny + nz * nz);float d = (nx + ny - nz) * nd * 0.5f + 0.5f;*p++ = ramp[(int)(d * 5.0f)];}else*p++ = ' ';}}for (sy = 0; sy < 25; sy++) {COORD coord = { 0, sy };SetConsoleCursorPosition(o, coord);WriteConsole(o, buffer[sy], 79, NULL, 0);}Sleep(33);}}

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_DEFAULT
PTHREAD_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_NONE
PTHREAD_PRIO_INHERIT
PTHREAD_PRIO_PROTECT
