//    co-unix.lnt
//    Compiler Options for Unix C



//    This file contains options to allow PC-lint to process source
//    files for your compiler.  It is used as follows:
//
//    lint  co-unix.lnt  source-file(s)
//

            // while processing compiler (library) header files ...
-wlib(1)    // sets the warning level within library headers to 1
	    // (no warnings, just syntax errors).  Comment out if you
	    // are actually linting library headers.  This
	    // option makes obsolete options of the form -elib(axxx) where
	    // xxx >= 400 which may be retained for historical reasons.
-elib(652)  // suppress message about #define of earlier declared symbols
-elib(762)  // suppress message about multiple identical declarations and
-elib(760)  // suppress message about multiple identical macro defs
-elib(553)  // undefined preprocessor variables are taken as 0
            // while processing library headers
-elib(607)   // parameter substitution within string
-elib(602)   // in dial.h there are comments within comments ?
-elib(537)   // repeated include files
-elib(2)     // unclosed quotes in nserve.h
-elib(123)   // size is both a variable and a macro with args

-si4    // int's are typically 4 bytes
-sp4    // ptr's are typically 4 bytes
-emacro(734,putc)   // don't complain about items being too large.
-emacro(413,offsetof)  // use of NULL pointer creates a stir
-emacro(545,offsetof)  // addressing an array member is OK
-emacro((???),va_arg)   // the va_arg() macro can yield 415, 416, 661, 662
			// 796 and 797 (out-of-bounds errors).

//  The following options were found necessary when processing
//  the Unix headers within /usr/include

-i/usr/include     // Set an include directory
+fdi            // Use the directory of the including file

+ppw(ident)     // Tolerate #ident

-di386=1    // needed for some Unix's
-a#machine(i386)  //  #assert's machine(i386)  (SVR4 facility).

//  Not all Unix systems are identical; please tailor to suit


//  The following functions exhibit variable return modes.
//  That is, they may equally-usefully be called for a value
//  as called just for their effects.  Accordingly we inhibit
//  Warning 534 for these functions.
//  Feel free to add to or subtract from this list.

-esym(534,close,creat,fclose,fprintf,fputc)
-esym(534,fputs,fscanf,fseek,fwrite,lseek,memcpy,memmove,memset)
-esym(534,printf,puts,scanf,sprintf,sscanf,strcat,strcpy)
-esym(534,strncat,strncpy,unlink,write)

// For non-ANSI compilers we suppress messages 515 and 516
// for functions known to have variable argument lists.
// For ANSI compilers, header files should take care of this.

-esym(515,fprintf,printf,sprintf,fscanf,scanf,sscanf)
-esym(516,fprintf,printf,sprintf,fscanf,scanf,sscanf)

-e746      // do not insist on prototypes

// The following options are required by most compilers to
// noiselessly process iostream.h

-elib(1717) //empty prototypes
-elib(522) //function return value ignored
-elib(1053) //prototypes cannot be distinguished
-elib(1721) //unusual operator =() declaration
-elib(1720) //assignment op has non-const parameter
-elib(655)  // bitwise operator combining compatible enum's
-elib(641)  // converting enum's to int
-elib(537)  // repeated include file (ios.h)
-elib(1511) // member (rdbuf) hides nonvirtual member
-elib(1712) // default constructor not defined for class
-elib(1736) // redundant access specifier
-esym(1702,operator<<,operator>>)  // both a member and an ordinary function

// These functions return things that are frequently ignored.

-esym(534,ostream::operator<<,istream::operator>>)

// The following additional options seem to be needed.

-fdc       // do not Distinguish plain Char as a unique type.
	   // i.e. char is either signed char or unsigned char
-elib(747) //significant prototype coercion
-elib(740) //unusual pointer casts
-elib(1029) //default argument repeated -- can't dist. char, signed char
-elib(1055) //call to rdbuf() questioned?
-elib(1708,1709) // minor C/C++ declaration conflict
