Os9fork create a process os9fork char *modname int paramsize char *paramptr int type int lang int datasize os9 F$FORK The action of F$FORK is desribed fully in the OS-9 System Programmer's Manual. Os9fork will create a process that will run concurrently with the calling process. When the forked process terminates, it will return to the calling process. "Modname" should point to the name of the desired module. "Paramsize" is the length of the parameter string which should normally be terminated with a '\n', and "paramptr" points to the parameter string. "Type" is the module type as found in the header(normally 1: program), and "lang" should match the language nibble in the module header (C programs have 1 for 6809 machine code here). "Datasize" may be zero, or it may contain the number of 256 byte pages to give to the new process as initial allocation of memory. -1 will be returned on error, or the ID number of the child process will be returned on success.
