size_ t fread(void *ptr, size_t size, size_t n, FILE *fp)
Description:
Header file:
Return values:
Parameters:
Example:
Remarks:
Inputs data from a stream input/output file to the specified storage area.
<stdio.h>
If size or n is 0: 0
If size and n are both nonzero: Number of successfully input members
ptr
size
n
fp
The fread function inputs n members whose size is specified by size, from the
#include <stdio.h>
void *ptr;
size_t size;
size_t n, ret;
FILE *fp;
stream input/output file indicated by file pointer fp, into the storage area pointed
to by ptr. The file position indicator for the file is advanced by the number of
bytes input.
The fread function returns the number of members successfully input, which is
normally the same as the value of n. However, at end-of-file or if an error
occurs, the number of members successfully input so far is returned, and so the
return value will be less than n. The ferror and feof functions should be used to
distinguish between end-of-file and error occurrence.
If the value of size or n is zero, zero is returned and the contents of the storage
area pointed to by ptr are unchanged. If an error occurs, or if only some of the
members can be input, the file position indicator will be undefined.
ret=fread(ptr, size, n, fp);
Pointer to storage area to which data is input
Number of bytes in one member
Number of members to be input
