pr_open(struct ps_prochandle *P,
const char *filename, int flags,
pr_open() function injects the open(2) system call into the target process P by means of the agent LWP. If the process handle P is the value
NULLthen this will be equivalent to calling open(2) on the currently running process.
pr_open() function only works on

processes, or ELF objects do not support system call injection.
pr_open() function's return value is that described in open(2). Otherwise, -1 is returned and errno is set to
ENOSYSto indicate that the system call could not be injected.
pr_open() function will fail if:
