New Message Exit Facility

In Chapter 2, "Function Categories," in the section titled, "Diagnostic Control Functions," add the following text after the first paragraph.

Additionally, the functions wmi_set and wmi_del allow you to define exits which control the processing of library diagnostics. You can define an exit to selectively suppress messgaes, to add text to messages, and to capture messages for your own processing, for example, writing them to a log file. Additionally, the functions wmifilte and wmifiltn are simple message exits to suppress specific messages, either by message number or by errno value. See the function writeups for more detailed information on writing library message exits.

Add the following diagnostic control functions to the existing list:

wmi_del cancel a previously requested message exit

wmi_set specify a message exit

wmifilte filter library messages by errno value

wmifiltn filter library messages by message number.

Add the following functions, wmi_del, wmifilte, wmifiltn, and wmi_set, to Chapter 6, "Function Descriptions."
