ltrace is a program that intercepts and records dynamic library calls by the executed process and the signals which are received by that process. It can also intercept and print the system calls executed by the program.
Example
This example has been taken from SUSE Linux 11.3:
tweedleburg:~ # yast -i ltrace
tweedleburg:~ # which ls
/bin/ls
tweedleburg:~ # ltrace /bin/ls
__libc_start_main(0x4077c0, 1, 0x7fffa594b778, 0x410440, 0x4104d0 <unfinished ...>
strrchr("/bin/ls", '/') = "/ls"
setlocale(6, "") = "LC_CTYPE=en_US.UTF-8;LC_NUMERIC="...
bindtextdomain("coreutils", "/usr/share/locale") = "/usr/share/locale"
textdomain("coreutils") = "coreutils"
__cxa_atexit(0x40a560, 0, 0, 0x736c6974756572, 0x619460) = 0
isatty(1) = 1
getenv("QUOTING_STYLE") = NULL
getenv("LS_BLOCK_SIZE") = NULL
