Description

The -Ldf option causes the Compiler to generate a text file that contains a list of the compiler-defined #define. The default filename is predef.h, but may be changed (e.g., -Ldf="myfile.h"). The file is generated in the directory specified by the TEXTPATH: Text File Path environment variable. The defines written to this file depend on the actual Compiler option settings (e.g., type size settings or ANSI compliance).

Note: The defines specified by the command line (-D: Macro Definition option) are not included.

This option may be very useful for SQA. With this option it is possible to document every #define which was used to compile all sources.

Note: This option only has an effect if a file is compiled. This option is unusable if you are not compiling a file.

Example

The following listing is an example which lists the contents of a file containing define directives.

/* resolved by preprocessor: __LINE__ */ 
/* resolved by preprocessor: __FILE__ */ 
/* resolved by preprocessor: __DATE__ */ 
/* resolved by preprocessor: __TIME__ */ 
#define __STDC__ 0 
#define __VERSION__ 5004 
#define __VERSION_STR__ "V-5.0.4" 
#define __SMALL__
