apptrace

- trace application function calls to Solaris shared libraries

Synopsis

apptrace [-f] [-F [!] tracefromlist] [-T [!] tracetolist] 
     [-o outputfile] [ [-tv] [!] call ,...] command 
     [command arguments]

Description

The apptrace utility runs the executable program specified by command and traces all function calls that the programcommand makes to the Solaris shared libraries. For each function call that is traceable, apptrace reports the name of the library interface called, the values of the arguments passed, and the return value.

By default, apptrace traces calls directly from the executable object to any of the shared objects it depends on. Indirect calls (that is, calls made between shared objects that the executable depends upon) are not reported by default.

Calls from or to additional shared objects may be traced using the -F or -T options (see below).

The default reporting format is a single line per call, with no formatted printing of arguments passed by reference or of data structures.

Formatted printing providing additional argument details is obtained using the -v option (see below).

By default, every interface provided by a shared object is traced if called. However, the set of interfaces to be traced can be restricted, using the -t and/or -v options.

Since it is generally possible to trace calls between any of the dynamic objects linked at runtime (the executable object and any of the shared objects depended upon), the report of each traced call gives the name of the object from which the call was made.

apptrace traces all of the procedure calls that occur between dynamic objects via the procedure linkage table, so only those procedure calls which are bound via the table will be traced. See the Linker and Libraries Guide.

Options

The following options are supported:

-f

Follows all children created by fork(2). This option will also cause the process id to be printed at the beginning of each line.

-F [!]tracefromlist

Traces calls from a comma-separated list of shared objects. Only calls from these shared objects will be traced. The default is to trace calls from the main executable only. Only the basename of the shared object is required. For example, libc will match /usr/lib/libc.so.1. Additionally, shell style wildcard characters are supported as described in fnmatch(5). A list preceded by a ``!'' defines a list of objects from which calls should not be traced. If the tracing of calls from command is required, then command must be a member of tracefromlist.

-o outputfile

apptrace output will be directed to the outputfile. By default, apptrace output is placed on the stderr stream of the process being traced.

-t [!]call, . . .

Traces or excludes function calls. Those calls specified in the comma-separated list call are traced. If the list begins with a !, the specified function calls are excluded from the trace output. The default is -t *. The use of shell style wildcards is allowed.

-T [!]tracetolist

Traces calls to a comma-separated list of shared objects. The default is to trace calls to all shared objects. As above, the basename is all that is required and wildcarding is allowed. A list preceded by a ``!'' denotes a list of objects to which calls should not be traced.

-v [!]call, . . .

Provides verbose, formatted output of the arguments and return values of the function calls specified (as above in the -t option). Unlike truss(1), calls named by the -v option do not have to be named by the -t option. For example, apptrace -v open is equivalent to truss -t open -v open.

** NR - The return value of a function call will not be traced.

Files

Basic runtime support for apptrace is provided by the link auditing feature of the Solaris runtime linker (ld.so.1(1)) and the apptrace command's use of this facility relies on an auditing object (apptrace.so.1) kept in /usr/lib/abi.

LIMITATIONS

In general, apptrace cannot trace calls to functions accepting variable argument lists. There has been some clever coding in several specific cases to work around this limitation, most notably in the printf and scanf families.

The apptrace utility can not trace the return value of a function call whose return type is a struct or union.

Functions that attempt to probe the stack or otherwise extract information about the caller cannot be traced. Some examples are [gs]etcontext(), [sig]longjmp(), [sig]setjmp(), and vfork().

Functions such as exit(2) that do not return will not be traced for their return values.

For security reasons, only those processes with appropriate privileges can use apptrace to trace setuid/setgid programs.

Tracing functions whose usage requires the inclusion of <varargs.h>, such as vwprintw(3XCURSES) and vwscanw(3XCURSES), will not provide formatted printing of arguments.
