Turbo C 2.0、Borland C++库函数及用例!

字母Ａ开头函数函数名: abort功 能: 异常终止一个进程用 法: void abort(void);程序例:#include <stdio.h>#include <stdlib.h>int main(void){printf("Calling abort()\n");abort();return 0; /* This is never reached */}函数名: abs功 能: 求整数的绝对值用 法: int abs(int i);程序例:#include <stdio.h>#include <math.h>int main(void){int number = -1234; printf("number:%d absolute value:%d\n",number,abs(number));return 0;}函数名: absread功 能: 绝对磁盘扇区读数据用 法: int absread( int drive, int nsects, int sectno,void *buffer );程序例:/* absread example */#include <stdio.h>#include <conio.h>#include <process.h>#include <dos.h>int main(void){int i, strt, ch_out, sector;char buf[512]; printf("Insert diskette into drive A press any key\n");getch();sector = 0;if (absread(0, 1, sector, &buf) != 0){ perror("Disk problem");exit(1); }printf("Read OK\n");strt = 3;for (i=0; i<80; i++){ ch_out = buf[strt+i];putchar(ch_out); }printf("\n");return(0); }函数名: abswrite功 能: 绝对磁盘扇区写数据用 法: int abswrite( int drive, int nsects, in tsectno,
