|
* 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
