小编给大家分享一下IO之Formatted IO的示例代码,希望大家阅读完这篇文章之后都有所收获,下面让我们一起去探讨吧!

Formatted I/O


/* ANSI */
/* write a formatted string to the standard output stream */int  printf(char *, ...);
/* write a formatted string to a buffer */int  sprintf(char *, char *, ...);
/* write a formatted string to a buffer, not exceeding buffer size */int  snprintf(char *, size_t, char *, ...);
/* write a formatted string to a stream */int  fprintf(FILE *, char *, ...);
/* write a formatted string to a stream */int  vfprintf(FILE *, char *, va_list);
/* write a string formatted with a variable argument list to standard output */int  vprintf(char *, va_list);
/* write a string formatted with a variable argument list to a buffer */int  vsprintf(char *, char *, va_list);
/* write a string formatted with a variable argument list to a buffer, not exceeding buffer size */int  vsnprintf(char *, size_t, char *, va_list);
/* write a formatted string to an output function */int  oprintf(OPRINTF_OUTPUT_FUNCPTR routine, _Vx_usr_arg_t arg, char *, ...);
/* write a formatted string to an output function */int  voprintf(OPRINTF_OUTPUT_FUNCPTR routine , _Vx_usr_arg_t arg, char *, va_list);
/* read and convert characters from the standard input stream */int  scanf(char *, ...);
/* read and convert characters from an ASCII string */int  sscanf(char *, char *, ...);
/* read and convert characters from a stream */int  fscanf(FILE *, char *, ...);

格式化的定义可以看这里

/* WRS functions declarations */
/* write a formatted string to a file descriptor */int  fdprintf(int, char *, ...);
/* write a string formatted with a variable argument list to a file descriptor */int  vfdprintf(int, char *, va_list);
/* write a formatted string to the standard error stream */int  printErr(char *, ...);
/* print an exception-generated error message */void printExc(char *, int, int, int, int, int);

当然了,还有kprintf
