The
pr_stat(),
pr_lstat(), and
pr_fast()
functions inject the stat(2),
lstat(2), and
fstat(2) system calls respectively into
the target process P by means of the agent LWP. If the
process handle P is the value
NULL then this will be equivalent to calling
stat(2),
lstat(2), or
fstat(2) on the currently running
process.
The arguments path, and
buf to the
pr_stat()
function have the same meaning as in
stat(2). See
stat(2) for the full description and
purpose of the
stat
system call and its arguments.
The arguments fd, and
buf to the
pr_fstat()
function have the same meaning as in
fstat(2), see
fstat(2) for the full description and
purpose of the
fstat
system call and its arguments.
The arguments path, and
buf to the
pr_lstat()
function have the same meaning as in
lstat(2), see
lstat(2) for the full description and
purpose of the
lstat
system call and its arguments.
The
pr_stat(),
pr_lstat(), and pr_fstat()
functions only work on active processes. Process handles that correspond to
core files, zombie processes, or ELF objects do not support system call
injection.
The
pr_stat64(),
pr_fstat64(),
and
pr_lstat64()
functions are equivalent to pr_stat(),
pr_fstat(), and pr_lstat()
respectively; however, rather than having the stat information be subject to
the data model of the target process, they always provide 64-bit stat
information. See lf64(7) for more
information.
Upon successful completion, the pr_stat()
function's return value is that described in
stat(2). Otherwise,
-1 is returned
and
errno is
set to ENOSYS to indicate that the system call could
not be injected.
For the full list of errors see the ERRORS section in stat(2).
The pr_stat() function will fail if:
ENOSYSSee LOCKING in libproc(3LIB).
