rpspawn - Spawn a LAM process onto a remote node.

#include <preq.h>

int rpspawn(int src_node, int dest_node, int sflags, int svalue, char **argv, int *pid, int *idx);

src_node: source node where selected process are running
dest_node: destination node where new process will be spawned
sflags: method by which the existing process is selected - See rpstate(2).
svalue: selection matching value, if required, otherwise ignored
argv: null-terminated array of strings to be passed as command-line arguments to the new process
pid: new process ID (output)
idx: new process index (output)

When a process is spawned, the program is copied and rerun as a new process.

If argv is the null pointer, the program arguments of the original process are used.

One and only one process is spawned by rpspawn(). If multiple processes are selected, only one process is chosen.

ENOPDESCRIPTORS: The remote process descriptor table is full.
ENOFLDESCRIPTORS: The table of strorage blocks (kept by the flat daemon) is full.
ENOTPROCESS: No matching process exists.
EINVAL: The selection method is invalid.
