Description:
Include:
Prototype:
Argument:
Remarks:
Example:
Resets the file pointer to the beginning of the file.

#include <stdio.h> /* for rewind, fopen, */
int main(void)
{
}
Output:
I have 10 cookies.
I ate 10 cookies.
FILE *myfile;
char s[] = "cookies";
int x = 10;
if ((myfile = fopen("afile", "w+")) == NULL)
else
{
}
printf("Cannot open afile\n");
fprintf(myfile, "%d %s", x, s);
printf("I have %d %s.\n", x, s);
/* set pointer to beginning of file */
rewind(myfile);
fscanf(myfile, "%d %s", &x, &s);
printf("I ate %d %s.\n", x, s);
fclose(myfile);
