1.4 Diagnostics

FunnelWeb indicates the level of severity of each diagnostic

that it issues by starting each diagnostic either with the full

name of the severity level or with just the first letter of the

severity level followed by a colon.

FunnelWeb conveys the presence or absence of diagnostics at

the operating system level by returning EXIT_SUCCESS status

if no diagnostics occurred during the run and EXIT_FAILURE

status if one or more diagnostics (including warnings) occurred

during the run. (From the symbols of the ANSI standard C

library stdlib.h. See 

[Kernighan88]

, p.252.)
