insert
Summary
#include <dataman/dataman.h>
insert(fmt,pos,idx_name);
int fmt, pos;
char *idx_name;
Description
The insert routine puts a new data record into a data
base file. The routine determines the file that contains
the record that the named index's MFRP points to and
inserts format number fmt. If fmt is less than 1 or
greater than the number of formats defined for the file
a diagnostic is displayed and the routine halts. The pos
argument is either of the manifest constants BEFORE or
AFTER. The constant BEFORE inserts the new record prior
to the MFRP and the constant AFTER inserts the record
after. If the index currently points to no record, the
diagnostic "initial GET not attempted" will appear and
the routine will terminate. Otherwise the record that is
currently in memory will be flushed, the new record,
consisting of all blanks, will be inserted in the file,
the MFRP moved to the new record, and the new blank
record read into memory. All fields will be blank. The
KP is unchanged.
Example
#include <dataman/dataman.h>
main(int argc,char *argv[])
{
key k_buff;
...
move(k_buff,num_key); /* build key */
get(num_ix,num_key) else { /* get rec */
pause(1,1,"Key not on file");
exit(0);
}
insert(1,BEFORE,num_ix); /* insert new rec */
....
}
