Release 4.9 scripts/docproc.c

Directory: scripts
/*
 *      docproc is a simple preprocessor for the template files
 *      used as placeholders for the kernel internal documentation.
 *      docproc is used for documentation-frontend and
 *      dependency-generator.
 *      The two usages have in common that they require
 *      some knowledge of the .tmpl syntax, therefore they
 *      are kept together.
 *
 *      documentation-frontend
 *              Scans the template file and call kernel-doc for
 *              all occurrences of ![EIF]file
 *              Beforehand each referenced file is scanned for
 *              any symbols that are exported via these macros:
 *                      EXPORT_SYMBOL(), EXPORT_SYMBOL_GPL(), &
 *                      EXPORT_SYMBOL_GPL_FUTURE()
 *              This is used to create proper -function and
 *              -nofunction arguments in calls to kernel-doc.
 *              Usage: docproc doc file.tmpl
 *
 *      dependency-generator:
 *              Scans the template file and list all files
 *              referenced in a format recognized by make.
 *              Usage:  docproc depend file.tmpl
 *              Writes dependency information to stdout
 *              in the following format:
 *              file.tmpl src.c src2.c
 *              The filenames are obtained from the following constructs:
 *              !Efilename
 *              !Ifilename
 *              !Dfilename
 *              !Ffilename
 *              !Pfilename
