/*
* Words, such as the parameters and results of system calls, are capable of
* being displayed in a number of different formats.
*
* fmt_none - indicates the absense of further arguments, functions that don't
* return a value, etc.
*
* The function format_value(..) can be used to display a word in one of the
* following formats.
*
* fmt_dec - a signed decimal number : 0, 21, -1
* fmt_hex - a unsigned hex number : 0x0, 0x15, 0xffffffff
* fmt_ptr - a pointer : NULL, 0x00000015, 0xffffffff
* fmt_fd - a file descriptor : fd0, fd15, fd-1
* fmt_signal - the name of a signal : 0, SIGTTIN, -1
* fmt_error - the name of an error : 0, EISDIR, -1
* fmt_open_flags - the flags to open : O_RDONLY, O_WRONLY|0x14, 0xffffffff
* fmt_unknown - representation unknown : .., .., ..
* fmt_string - if the null termintated string at word is printable displays
* the string within quotes, otherwise displays like fmt_ptr
* fmt_post_string - displays like fmt_ptr, value of word is also saved,
* following the system call a printable string exists at
* address word the address and the string will be displayed
* fmt_data - only permitted in argument lists, next argument must be
* format_data_size, if printable data exists at word having length
* specified by the next argument it is printed, otherwise displays
* like fmt_ptr
* fmt_data_size - displays like FMT_SIZE
* fmt_post_data - displays like fmt_ptr, value of word is also saved,
* following call if a printable length delimited string exists
* it will be displayed
* fmt_post_data_size - displays like FMT_SIZE, value is saved for use as
* length for fmt_post_data display format
* fmt_string_array - word is the address of a null terminted array of strings
* to be printed if possible
*
* Unlike the string formats which typically represent filenames it is not so
* important that length delimited data be fully displayed. When printable,
* it will be truncate much more harshly than the string formats.
*
* Only one item can be pending for display at the end of a system call.
*
* At a later date this program may be extended to display length delimited
* data as a hex dump if it is not printable.
*
* The following macros are employed to make it easy to alter how a whole
* class of values is displayed by changing their definition.
*
* FMT_STATUS - function calls that return 0 on success and -1 on error
* FMT_FLAGS - bit field objects
* FMT_SIZE - length of an object in bytes
