STRICT
The STRICT pragma directs the TNS C compiler or Cfront to generate a warning if it
encounters one of a number of valid, but questionable, syntactic or semantic
constructs.
The pragma default settings are:
Usage Guidelines
•
The STRICT pragma can be entered on the compiler RUN command line or in the
source text.
•
The STRICT pragma causes these additional warning messages to be issued: 5,
36, 84, 92, 93, 94, 96, 98, 105, 107, 108, 119, 148, 151, 179, 217, and 218. For
information about messages, see Section 20, TNS C Compiler Messages.
•
The constructs that the STRICT pragma causes the compiler to diagnose include:
°
Function declarations and definitions that do not use function-prototype syntax
°
Calls to functions that do not have a function-prototype declaration or definition
in scope
°
Calls to functions that have no nonprototype declaration or definition in scope
°
Calls to library routines that occur before inclusion of the library header that
declares or defines the routine
°
Object declarations that do not include a type specifier
°
Nonprototype function definitions that do not specify the types of all parameters
°
A type conversion that might cause loss of data or precision without an explicit
cast expression
°
Access of the value of a local variable before it appears to have been initialized
°
A constant used as the controlling condition of a do, for, if, switch, or
while statement or of a conditional expression (using the ?: operator)
