NAME


sotruss - trace shared library procedure calls

SYNOPSIS


/usr/bin/sotruss [-f] [-F bindfromlist] [-T bindtolist]
[-o outputfile] executable [executable arguments...]


DESCRIPTION


sotruss executes the specified command and produces a trace of the
library calls that it performs. Each line of the trace output reports
what bindings are occurring between dynamic objects as each procedure
call is executed. sotruss 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 Procedure Linkage Table will be
traced. See Linker and Libraries Guide

OPTIONS


-F bindfromlist
A colon-separated list of libraries that are to be
traced. Only calls from these libraries will be
traced. The default is to trace calls from the main
executable only.


-T bindtolist
A colon-separated list of libraries that are to be
traced. Only calls to these libraries will be traced.
The default is to trace all calls.


-o outputfile
sotruss output will be directed to the outputfile. If
this option is combined with the -f option then the
pid of the executing program will be placed at the end
of the filename. By default sotruss output is placed
on stderr.


-f
Follow all children created by fork() and print
truss output on each child process. This option will
also cause a pid to be output on each truss output
line.


EXAMPLES


Example 1: An example of sotruss.




A simple example shows the tracing of a simple ls command:


% sotruss ls | more
ls -> libc.so.1:*atexit(0xef7d7d1c, 0x23c00, 0x0)
ls -> libc.so.1:*atexit(0x1392c, 0xef7d7d1c, 0xef621bb0)
ls -> libc.so.1:*setlocale(0x6, 0x1396c, 0xef621ba8)
ls -> libc.so.1:*textdomain(0x13970, 0x1396c, 0xef621ba8)
ls -> libc.so.1:*time(0x0, 0xef61f6fc, 0xef621ba8)
ls -> libc.so.1:*isatty(0x1, 0xef61f6fc, 0x0)
ls -> libc.so.1:*getopt(0x1, 0xeffff8fc, 0x13980)
ls -> libc.so.1:*malloc(0x100, 0x0, 0x0)
ls -> libc.so.1:*malloc(0x9000, 0x0, 0x0)
ls -> libc.so.1:*lstat64(0x23ee8, 0xeffff7a0, 0x0)
...
ls -> libc.so.1:*printf(0x13a64, 0x26208, 0x23ef0)
ls -> libc.so.1:*printf(0x13a64, 0x26448, 0x23ef0)
ls -> libc.so.1:*exit(0x0, 0x24220, 0x2421c)
