可以作為函數(shù)名的是?
函數(shù)名: abort
功 能: 異常終止一個(gè)進(jìn)程
用 法: void abort(void);
程序例:
#include
#include
int main(void)
{ printf("Calling abort()\n");
abort();
return 0; /* This is never reached */
}
函數(shù)名: abs
功 能: 求整數(shù)的絕對(duì)值
用 法: int abs(int i);
程序例:
#include
#include
int main(void)
{ int number = -1234;
printf("number: %d absolute value: %d\n", number, abs(number)); return 0;
}
函數(shù)名: absread, abswirte
功 能: 絕對(duì)磁盤扇區(qū)讀、寫數(shù)據(jù)
用 法: int absread(int drive, int nsects, int sectno, void *buffer); int abswrite(int drive, int nsects, in tsectno, void *buffer);
程序例:
/* absread example */
#include
#include
#include
#include
int main(void)
{ int i, strt, ch_out, sector;
char buf[512];
printf("Insert a diskette into drive A and 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);
}
函數(shù)名: access
功 能: 確定文件的訪問權(quán)限
用 法:
