fgetpos
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Gets the stream's file position.
<stdio.h>
int fgetpos(FILE *stream, fpos_t *pos);
stream
pos
Returns 0 if successful; otherwise, returns a non-zero value.
The function stores the file-position indicator for the given stream in
*pos if successful, otherwise, fgetpos sets errno.
/* This program opens a file and reads bytes at */
/* several different locations. The fgetpos
/* function notes the 8th byte. 21 bytes are
/* read then 18 bytes are read. Next the
/* fsetpos function is set based on the
/* fgetpos position and the previous 21 bytes
/* are reread.
#include <stdio.h> /* for fgetpos, fread,
int main(void)
{
}
Output:
Bytes read: program opens a file
Bytes read: and reads bytes at
Bytes read: program opens a file
FILE
fpos_t pos;
char
if ((myfile = fopen("sampfgetpos.c", "rb")) ==
else
{
if (fsetpos(myfile, &pos) != 0)
fread(buf, sizeof(char), 21, myfile);
printf("Bytes read: %.21s\n", buf);
fclose(myfile);
}
fread(buf, sizeof(char), 8, myfile);
printf("Cannot open file\n");
if (fgetpos(myfile, &pos) != 0)
else
{
}
perror("fsetpos error");
perror("fgetpos error");
fread(buf, sizeof(char), 21, myfile);
printf("Bytes read: %.21s\n", buf);
fread(buf, sizeof(char), 18, myfile);
printf("Bytes read: %.18s\n", buf);
