PURPOSE
Gather an array into a record
SYNONYM
api_dbf_gather()
SYNOPSIS
#include "dbapi.h" char *DBF_GATHER(fldbuf) <input parameters> char fldbuf[ ]; /* Pointer to an array containing values to update from */ <output parameters> none
DESCRIPTION
The DBF_GATHER() function will update the current record with the contents of the specified array. The number of array elements must match the number of fields in the database to be updated.
Recital converts the character array elements automatically to the data type of each field in the record. Memo and Blob fields are not updated with the DBF_GATHER() function, however an array element must still be defined for these fields.
EXAMPLE
The following example updates the second record in the "example.dbf" database from the specified array. See Appendix A for the data structure of "example.dbf".
#include "dbapi.h" dbapi_dbf_gather() { int rc; int element_no; char *fldbuf[12]; char blob[5]; char byte[3]; char character[21]; char date[9]; char dfloat[11]; char integer[5]; char logical[2]; char number[11]; char memo[5]; char real[11]; char word[11]; char zoned[11]; strcpy(blob,"blob"); strcpy(byte,"2"); strcpy(character, "Record number 2"); strcpy(date, "19990112"); strcpy(dfloat, "2.22"); strcpy(integer, "2"); strcpy(logical, "T"); strcpy(number, "2.22"); strcpy(memo, "memo"); strcpy(real, "2.22"); strcpy(word, "2.22"); strcpy(zoned, "2.22"); fldbuf[0] = blob; fldbuf[1] = byte; fldbuf[2] = character; fldbuf[3] = date; fldbuf[4] = dfloat; fldbuf[5] = integer; fldbuf[6] = logical; fldbuf[7] = number; fldbuf[8] = memo; fldbuf[9] = real; fldbuf[10] = word; fldbuf[11] = zoned; rc = COMMAND("use example"); if (rc == 0) { DBF_GOTO(2); if (!DBF_ISEXCLUSIVE()) DBF_LOCKR(DBF_RECNO()); rc = DBF_GATHER(fldbuf); rc = DBF_UPDATE(); if (!DBF_ISEXCLUSIVE()) DBF_UNLOCKR(DBF_RECNO()); COMMAND("use"); } _retni(rc); }
