Hello,
I have a sample program for the same , But I am not sure how I can
upload it , as to compile that program btrieve(pervasive) library and
header files are also required.
Can I attach source code here ?
Problem is always getting recreated if I open Btrieve file in child
process after fork()
---in main process fork is called-
iStat = fork();
printf("\nCreating Clients using fork method iStat is %d...\n",iStat);
if ((iStat) == 0 )
{
printf("\n I am in child \n");
rd_proc_wr_request();
printf("\n I am in child exit \n");
exit(0);
}
/*when the process client finishes Kill the child */
else
{
/*We are the parent so free the memory*/
sleep(15);
printf("start of Main Process \n");
//wait(NULL);
errWaitPid = waitpid( iStat, &wstatus, WNOHANG | WUNTRACED | WCONTINUED );
printf( "errWaitPid = %d, errno = %d, comment = %s\n", errWaitPid,
errno, strerror( errno ) );
printf ("Parent reads <%s>\n",shm) ;
printf("Exiting Main Process\n");
exit(0);
}
this is child process code---
static void* rd_proc_wr_request()
{
/* Btrieve function parameters */
BTI_BYTE posBlock1[128];
BTI_BYTE posBlock2[128];
BTI_BYTE dataBuf[255];
BTI_WORD dataLen;
BTI_BYTE keyBuf1[255];
BTI_BYTE keyBuf2[255];
BTI_WORD keyNum = 0;
BTI_BYTE btrieveLoaded = FALSE;
BTI_LONG personID;
BTI_BYTE file1Open = FALSE;
BTI_BYTE file2Open = FALSE;
BTI_SINT status;
BTI_SINT getStatus = -1;
BTI_SINT i;
BTI_SINT posCtr;
CLIENT_ID clientID;
VERSION_STRUCT versionBuffer[3];
FILE_CREATE_BUF fileCreateBuf;
GNE_BUFFER_PTR gneBuffer;
PERSON_STRUCT personRecord;
printf("This is child process...\n");
printf("Btrieve before B_OPEN status with BTRV (sample.btr) = %d\n", status);
memset(dataBuf, 0, sizeof(dataBuf));
memset(keyBuf1, 0, sizeof(keyBuf1));
memset(keyBuf2, 0, sizeof(keyBuf2));
strcpy((BTI_CHAR *)keyBuf1, FILE1_NAME);
strcpy((BTI_CHAR *)keyBuf2, FILE2_NAME);
status = BTRV(
B_OPEN,
posBlock1,
dataBuf,
&dataLen,
keyBuf1,
keyNum);
printf("Btrieve B_OPEN status (sample.btr) = %d\n", status);
