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)
