29 * the central header file included by all amanda sources
39 * I would prefer that each Amanda module include only those system headers
40 * that are locally needed, but on most Unixes the system header files are not
41 * protected against multiple inclusion, so this can lead to problems.
43 * Also, some systems put key files in different places, so by including
44 * everything here the rest of the system is isolated from such things.

464 * Voodoo time. We want to be able to mark these calls with the source
465 * line, but CPP does not handle variable argument lists so we cannot
466 * do what we did above (e.g. for alloc()).
468 * What we do is call a function to save the file and line number
469 * and have it return "false". That triggers the "?" operator to
470 * the right side of the ":" which is a call to the debug version of
471 * vstralloc/newvstralloc but without parameters. The compiler gets

474 * xx = vstralloc(a,b,NULL);

482 * function (but you should not do that because it creates a memory leak).

627 * Utility string macros. All assume a variable holds the current
628 * character and the string pointer points to the next character to
629 * be processed. Typical setup is:
633 * skip_whitespace(s, ch);
636 * If you advance the pointer "by hand" to skip over something, do
642 * Note that ch has the character at the end of the just skipped field.
643 * It is often useful to terminate a string, make a copy, then restore
644 * the input like this:
646 * skip_whitespace(s, ch);
647 * fp = s-1; ## save the start
648 * skip_nonwhitespace(s, ch); ## find the end
649 * p[-1] = '\0'; ## temporary terminate
650 * field = stralloc(fp); ## make a copy
651 * p[-1] = ch; ## restore the input
653 * The scanning macros are:
655 * skip_whitespace (ptr, var)
656 * -- skip whitespace, but stops at a newline
657 * skip_non_whitespace (ptr, var)
658 * -- skip non whitespace
659 * skip_non_whitespace_cs (ptr, var)
660 * -- skip non whitespace, stop at comment
661 * skip_integer (ptr, var)
662 * -- skip an integer field
663 * skip_line (ptr, var)
664 * -- skip just past the next newline
668 * ptr -- string pointer
669 * var -- current character
671 * These macros copy a non-whitespace field to a new buffer, and should
672 * only be used if dynamic allocation is impossible (fixed size buffers
673 * are asking for trouble):
675 * copy_string (ptr, var, field, len, fldptr)
676 * -- copy a non-whitespace field
677 * copy_string_cs (ptr, var, field, len, fldptr)
678 * -- copy a non-whitespace field, stop at comment
682 * ptr -- string pointer
683 * var -- current character
684 * field -- area to copy to
685 * len -- length of area (needs room for null byte)
686 * fldptr -- work pointer used in move
687 * if NULL on exit, the field was too small for the input

909 * In some Unix systems, basegid is defined as a gid_t; in others
910 * it is defined as an int. On Mac OS X, there is a "pre-compiled"
911 * unistd.h which causes the gcc -E command in the ICE_CHECK_DECL
912 * autoconf macro to not succeed. Thus, on Mac OS X, configure thinks
913 * we don't have this declaration when we actually do. Since Mac OS X
914 * defines basegid as an int, this declaration causes a compilation
915 * failure. The path of least resistance for fixing this problem
916 * is to just change the basegid declaration from gid_t to int, since
917 * other (but not all) UNIX flavors also defined basegid as an int.
