Sigh... per my (much) earlier post, please check out 'man strace'
Following are excerpts from the man intro:
"It intercepts and records the system calls which are called by a
process and the signals which are received by a process. The name of
each system call, its arguments and its return value are printed on
standard error or to the file specified with the -o
option."
"...a close examination of this boundary is very useful for bug
isolation, sanity checking and attempting to capture race conditions."
"Each line in the trace contains the system
call name, followed by its
arguments in parentheses and its return value."
If a program fails, strace shows the point at which it failed and the
process involved.
