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

pr_gettaskidinject gettaskid system call into victim process

Process Control Library (libproc, -lproc)

#include <libproc.h>

pr_gettaskid(struct ps_prochandle *P);

The () function injects the gettaskid(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 gettaskid(2) on the currently running process.

The () 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_gettaskid() function's return value is that described in gettaskid(2). Otherwise, is returned and 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 gettaskid(2).

The pr_gettaskid() 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.

See in libproc(3LIB).
