pr_getprojid(struct ps_prochandle *P);

The pr_getprojid() function injects the getprojid(2) system call into the target process P by means of the agent LWP. If the process handle P is NULL then this is equivalent to calling getprojid(2) on the currently running process.

The pr_getprojid() 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_getprojid() function's return value is that described in getprojid(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 getprojid(2).

The pr_getprojid() 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.
