void rewind(FILE* stream);
A call to rewind(stream) is equivalent to a call to fseek(stream, 0, SEEK_SET), except that end-of-file and error indicators are cleared.
It is defined in <cstdio> header file.
rewind() Parameters
stream: The file stream to reset the error flags and EOF indicator.
rewind() Return value
None.
Example: How rewind() function works
#include <cstdio>
int main()
{
int c;
FILE *fp;
fp = fopen("file.txt", "r");
if (fp)
{
while ((c = getc(fp)) != EOF)
putchar(c);
rewind(fp);
putchar('\n');
while ((c = getc(fp)) != EOF)
putchar(c);
}
fclose(fp);
return 0;
}When you run the program, the output will be:
