JBC API for TAFC Logger

This section explains the functionality of JBC API, which is a wrapper for TAFC logger. JBC API enables the JBASE BASIC code to use TAFC logger library. It works similar to TAFC logger library and provides you a function to generate logging at different levels shown below.

• TAFC_LOG_INFO
• TAFC_LOG_WARNING
• TAFC_LOG_ERROR
• TAFC_LOG_FATAL

TAFC logger can use the same set of logger variables in tafc.ini. You can however configure the JBC logger variable using [jBC] section.

Logger("ACCOUNT", TAFC_LOG_WARNING, "Test Program for JBC-ACCOUNT")
Logger("FUND-TRANSFER", TAFC_LOG_ERROR, "Test Program for JBC-FUND-TRANSFER"
