Thread: Buffer Problems?

I dont understand why this is happening, but this code will only write 1000 RECORD_STRUCT's to a file when I want it to write 2000, or 10000, or 30000, or N+1000 (with N >= 1) records.

WEIRD.

fseek, fwrite, and ferror do not return errors.

I know I dont need to seek, but I thought I would just slap that in there for the sake of debugging.

Am I missing something here?
Am I writing too fast?

Code:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>


typedef struct
{
	char name[32];
	char phone[16];
}RECORD_STRUCT;

int main(int argc, char * argv[])
{
	int i = 0;
	FILE * outFile = NULL;
	RECORD_STRUCT rs;
	char lbuf[10];
	int x;

	memset(&rs, 0x0, sizeof(RECORD_STRUCT));
	memset(lbuf, 0x0, 10);

	outFile = fopen("c:\\testNrecords.rkw", "w+b");

	if(outFile == NULL)
	{
		printf("null file!\n");
		return 0;
	}

	for(; i < 2000; i++)
	{

		sprintf(lbuf, "record #%d", i);
		strcpy(rs.name, lbuf);

		memset(lbuf, 0x0, 10);

		sprintf(lbuf, "phone #%d", i + 5);
		strcpy(rs.phone, lbuf);

		fseek(outFile, i * sizeof(RECORD_STRUCT), SEEK_SET);
		fwrite(&rs, sizeof(RECORD_STRUCT), 1, outFile);
	}

	fclose(outFile);

	return 0;
}
