pr_gettaskid(struct ps_prochandle *P);
The pr_gettaskid() 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 pr_gettaskid() 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, -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 gettaskid(2).
The pr_gettaskid() 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.

SYNOPSIS
#include <libproc.h>

pr_gettaskid(struct ps_prochandle *P);
DESCRIPTION
The pr_gettaskid() 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 pr_gettaskid() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects
do not support system call injection.
RETURN VALUES
Upon successful completion, the pr_gettaskid() function's return value
is that described in gettaskid(2). Otherwise, -1 is returned and errno
is set to ENOSYS to indicate that the system call could not be
injected.
ERRORS
For the full list of errors see the ERRORS section in gettaskid(2).
The pr_gettaskid() 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.
