46 * support lots more Linux syscalls
48 * add IPX and IPIP support

52 Changes in version 3.1
53 ======================
56 * Linux 68k is supported
57 * Linux alpha is supported
58 * configure is upgraded to autoconf 2.x
59 * using -f in combination with -e now works correctly
60 * output can be piped to a program
61 * tracing setuid programs works better
62 * it is now reasonable to install strace setuid to root in some circumstances
63 * new useful tracing names like file and process to trace whole
64 classes of system calls, e.g. -efile traces all system calls that
65 take a file name as an argument
66 * IPC calls on SunOS 4.1.x are decoded
67 * Linux program memory is reliably dereferenced
68 * Linux decodes at least the name of all syscalls as of pre2.0.4
69 * various cosmetic changes and bug fixes
71 Changes from versions 2.x to version 3.0
72 ========================================
74 * filename arguments are neither abbreviated nor stringified
75 * string arguments are now true C strings using octal instead of hex by default
76 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
77 * by default the output for multiple processes now goes into one file
78 * all structures, vectors, bitsets, etc. use consistent output formats
79 * the -c option now means count calls, -i does what the old -c used to do
81 New Features in version 3.0
82 ===========================
84 * non-ascii strings can be optionally printed entirely in hex
85 * the output format is readable when mutiple processes are generating output
86 * exit values are printed in an alignment column
87 * is is possible to suppress messages about attaching and detaching
88 * various tracing features can be enabled on a per syscall/signal/desc basis
89 * selective tracing of syscalls
90 * selective printing of syscall structures
91 * selective abbreviation of long structures on a per syscall basis
92 * selective printing of raw syscall arguments and results
93 * selective tracing of signals
94 * selective dumping of all I/O read from file descriptors
95 * selective dumping of all I/O written to file descriptors
96 * optional counting of time, calls, and errors for each syscall
