Status Array
|
  
|
|
|
|
Whenever any OmniAccess routine is executed, information
about the execution of that routine is returned to the status
array. This information includes error numbers, qualifying
counts, instance and cursor numbers as well as other pieces
of information used internally by OmniAccess.
The status arrary structure is declared in the oa.h file
and contains 10 named integers, 32 generic integers, and 6
types of character buffers.
The first ten elements return the same information for all
OmniAccess routines, although they may not apply to all routines.
For example, element 4 contains a qualifying count for routines
like oaqualify
and oajoin. But a
qualifying count is meaningless for routines like oaconnect
and oaopencursor.

oastatus_t is a type declaration for the OmniAccess status
array, which is used in newarly all OmniAccess routines
typedef struct oastatus
{ |
|  int
|
error; |
| int |
warn; |
| int |
info; |
| int |
count; |
| int |
bufflen; |
| int |
instance; |
| int |
cursor; |
| int |
transaction; |
| int |
cpu; |
| int |
elapsed; |
| int |
data[32]; |
| char |
buffer[256]; |
| char |
native_error[256]; |
| char |
location[256]; |
| char |
context[256]; |
| char |
msgs[8][256]; |
| char |
reserved[1024]; |
| } oastatus_t; |
- warn - This element contains the error condition for the
executed OmniAccess routine. This is a 32-bit signed integer
representing an error code contained in the global environment
file or OAGLOBAL.
If this element contains something other than 0 (Successful
completion), then something has happened that is severe
enough that requires the application to address the condition.
For example, a syntax error, invalid or inaccessible tables,
or end of data.
In this case, the application should call oaerror
to obtain the error message and any additional available
information.
- info - This element contains the warning condition for
the executed OmniAccess routine. This is a 32-bit signed
integer representing a warning code contained in the oaglobal
environment file.
If this element contains something other than 0 (Successful
completion), then something has happened that the application
may wish to know about, though it is not severe enough that
the application is required to address the condition. For
example, fewer rows were returned than were requested.
A call to oaerror with the WARN option, will return the
message corresponding to the warning code.
The following status array structure is supported for backward
compatibility.
typedef struct oastatus_30600
{ |
int |
error; |
int |
warn; |
int |
info; |
| int |
count; |
int |
bufflen; |
int |
instance; |
int |
cursor; |
int |
transaction; |
int |
data[6]; |
char |
buffer[36]; |
} oastatus_30600_t; |
