argument
description
_DBMS* F_Search
The file’s searching structure that has been
initialized.
char* field
String data wanted to match.
int search_fieldno
Field wanted to search.
int recordno
Begin to search from which data.
int get_field_no
After contrasting success, acquiring the
data of appointed field in this record.
char* F_Buffer
After contrast success, it will write record
which included this field into buffer.
int flag
FORWARD => Search from forward to
backward
BACKWARD => Search from backward to
forward
As success of searching, the file index will
stay in successful record front. When
search defeat, the file index will not be
moved.
Returns：
When “F _ Buffer = NULL”, pass back – 1: Search defeat; Pass other
value back: That is the size of space for buffer.
When “F _ Buffer ≠ NULL”, pass back – 1: Search defeat; Pass other
value back: That is the record position which confirm to contrast data.
Purpose：
Search the designated field. The field’s information include field string
and field number.You can write many fields in this field buffer. After
searching success, acquiring the appointed field in including this field’s
record.
Syntax： int SearchMultiField_GF(_DBMS* F_Search, char* multi_field, int
recordno, int get_field_no, char* F_Buffer, int flag);
Example call：
char str[20]=”00001,0;abcdefg,1”,str_buffer[60];
SearchMultiField_GF(&fsearch, str, 0,3,str_buffer,FORWARD);
Includes：
