Status Codes

45: The specified key flags are invalid

The key flags specification on a Create operation is inconsistent. If a

key has multiple segments, the duplicate, modifiable, and null

attributes should be the same for each segment in the key. Also, you

cannot use the null or manual key attributes in a key-only file. The

MicroKernel also returns this status code if the application

attempted to specify a different Alternate Collating Sequence (ACS)

for two or more segments of a segmented key.

46: Access to the requested file is denied

The MicroKernel returns this status code for the following reasons:

 The application opened a file in Read-only mode and tried to

perform a Write operation on that file.

 The application attempted to perform a Write operation on a file

that is flagged read-only by the operating system.

 When the application opened the file, it did not correctly specify

the owner name required for updates.

 (Workgroup engine only) If a Workgroup engine user or task

opens a file that a client machine has opened using a server

MicroKernel, the MicroKernel returns this status code if the

Workgroup engine user attempts to write to the file.

 (9.x and higher engines only) The application attempted to

perform a Write operation on a 5.x format file. When using a 9.x

or higher engine, you cannot perform a write operation such as

insert or delete on a 5.x format file.

47: The number of files opened exceeds the maximum

allowed

This status code is obsolete in MicroKernel versions 6.0 and later.

Pre-v6.0 workstation MicroKernels return this status code when the

number of files opened in Accelerated mode exceeded the number of

buffers available in the MicroKernel cache. When a file is opened in

Accelerated mode, the MicroKernel reserves one of its cache buffers

for the file. It always reserves five empty buffers for index

manipulation. Reconfigure Btrieve with both a smaller /P

configuration option (to allocate more buffers) and a larger /M

option (to increase the cache allocation).
