is returned in the usMaxBufs field of the configuration parameters returned in

response to a

dlPoll for system configuration. Operationally, this value limits the

number of buffers the user can have outstanding using the

dlBufAlloc function. If

not explicitly defined in the DLI configuration file, the

MaxBuffers parameter

defaults to 1024.

MaxBufSize — This parameter has been added to the “main” section. It replaces the

MaxBufSize parameter previously defined in the TSI configuration file. This value

is returned in the

iMaxBufSize field of the configuration parameters returned in

response to a

dlPoll for system configuration. Operationally, this value represents

the greatest size an application can request using

dlRead, and defines the buffer

size used when a

dlRead request is made without specifying a buffer (the API allo-

cates and returns this buffer to the application). If not explicitly defined in the

DLI configuration file, the

MaxBufSize parameter defaults to 1024.

MaxBufSize — This parameter has been defined in the “session” section of the DLI con-

figuration file. It replaces the

MaxBufSize parameter previously defined in the TSI

configuration file (“connection” section). This value is returned in the

usMaxSessBufSize field of the session parameters returned in response to a dlPoll

for session status. Operationally, this value represents the greatest size an applica-

tion can request to be written using

dlWrite. If not explicitly defined in the DLI

configuration file, the

MaxBufSize parameter defaults to 1024.

TSICfgName — The TSI configuration file is no longer used.

3.3.4 Logging and Tracing

The DLITE logging and tracing is similar to that supported in the Freeway environ-

ment. The Freeway maintains trace and log files internally according to the log and trace

levels defined in the DLI configuration file. Files are circular in nature and are written

to disk when the user application calls the

dlTerm function.

There is no longer any need to “decode” the DLI trace file.
