Q. Returns information about present virtual machine?

int pvm_parent( void )

Returns the tid of process which spawned the calling process.

int pvm_tidtohost( tid )

Returns the host of particular PVM process. Error if negative value is returned.

int pvm_config( int *nhost, int *narch, struct pvmhostinfo **hostp )

struct pvmhostinfo {

int hi_tid;

char *hi_name;

char *hi_arch;

int hi_speed;

};

Returns information about present virtual machine configuration. nhost is number of hosts (pvmds) in virtual machine. narch is number of various data formats being used. hostp is a pointer to an array of structures that comprises the information about every host comprising its pvmd task ID, architecture, relative speed and name (default is 1000).
