fseek
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Moves file pointer to a specific location.
<stdio.h>
int fseek(FILE *stream, long offset, int mode);
stream
offset
mode
Returns 0 if successful; otherwise, returns a non-zero value and set
errno.
mode can be one of the following:
SEEK_SET – seeks from the beginning of the file
SEEK_CUR – seeks from the current position of the file pointer
SEEK_END – seeks from the end of the file
#include <stdio.h> /* for fseek, fgets,
int main(void)
{
FILE *myfile;
char s[70];
int
myfile = fopen("afile.out", "w+");
if (myfile == NULL)
else
{
printf("Cannot open afile.out\n");
fprintf(myfile, "This is the beginning, "
y = fseek(myfile, 0L, SEEK_SET);
if (y)
else
{
}
y = fseek(myfile, 2L, SEEK_CUR);
if (y)
else
{
}
perror("Fseek failed");
fgets(s, 22, myfile);
printf("\"%s\"\n\n", s);
perror("Fseek failed");
fgets(s, 70, myfile);
printf("\"%s\"\n\n", s);
