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

pr_meminfoinject meminfo system call into victim process

Process Control Library (libproc, -lproc)

#include <libproc.h>

pr_meminfo(struct ps_prochandle *P, const uint64_t *addrs, int addr_count, const uint_t *info, int info_count, uint64_t *outdata, uint_t *validity);

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

The arguments addrs, addr_count, info, info_count, outdata, and validity have the same meaning as in meminfo(2). See meminfo(2) for the full description and purpose of the system call and its arguments.

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_meminfo() function's return value is that described in meminfo(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 meminfo(2).

The pr_meminfo() 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).
