remove
Summary
#include <dataman/dataman.h>
remove(k_buff, idx_name) else ...
key k_buff;
char *idx_name;
Description
int db_rm_key(k_buff, idx_name)
This function removes a key from the specified index. The
syntax for the original EDITOR command is:
remove key from idx_name.
It does NOT delete the associated data record. The argument
idx_name is the name of the index to operate on, and k_buff
is a key type containing the key to be removed. The key
must be constructed exactly as for the get procedure,
using the mk_key function. If there are duplicate keys in
the index, the function removes the first occurrence of
the first matching key, unless a system KEY was used for
the key argument. If the removed key is being pointed to
by any index's KP, any subsequent get_next, or get_prior
will issue a diagnostic and the process will terminate.
If the index was saved, an attempt to restore it will
generate an error as well. The get_current function
would return false for this case.
Example
#include <dataman/dataman.h>
main(int argc, char *argv[])
{
key k_buff;
...
mk_key(k_buff,patient_no,strlen(patient_no));
remove(number_ix,k_buff) else
pause(10,10,"Patient number not on file");
...
}
