PR_SETTASKID(3PROC) Process Control Library Functions PR_SETTASKID(3PROC)

pr_settaskid
inject settaskid system call into victim process

taskid_t
pr_settaskid(struct ps_prochandle *P, projid_t project, int flags);

The pr_settaskid() function injects the settaskid(2) system 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 settaskid(2) on the currently running process.

The arguments project and flags have the same meaning as in settaskid(2). See settaskid(2) for the full description and purpose of the settaskid system call and its arguments.

The pr_settaskid() 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_settaskid() function's return value is that described in settaskid(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 settaskid(2).

The pr_settaskid() function will fail if:

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.
