The pr_getsockopt() function injects the getsockopt(3SOCKET) library
call call 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 getsockopt(3SOCKET) on the currently running process.
The arguments sock, level, optname, optval, and optlen have the same
meaning as in getsockopt(3SOCKET), see getsockopt(3SOCKET) for the full
description and purpose of the getsockopt system call and its
arguments.
The pr_getsockopt() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects
do not support system call injection.
Upon successful completion, the pr_getsockopt() function's return value
is that described in getsockopt(3SOCKET). 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
getsockopt(3SOCKET).
The pr_getsockopt() function will fail if:
ENOSYS An error occurred while trying to invoke the agent
lwp and inject a system call in the process handle P
or the process handle P does not support system call
injection.
