NAME

       pvm_mytid - Returns the tid of the calling process.

SYNOPSIS

       C    int tid = pvm_mytid( void )

       Fortran   call pvmfmytid( tid )

PARAMETERS

       tid     Integer returning the task identifier of the calling PVM process.  Values less than zero indicate
               an error.

DESCRIPTION

       The routine pvm_mytid enrolls this process into PVM on its first call. It also generates a unique tid  if
       this  process  was not created by pvm_spawn.  pvm_mytid returns the tid of the calling process and can be
       called multiple times in an application.

       Any PVM system call (not just pvm_mytid) will enroll a task in PVM if the task is not enrolled before the
       call.

       The tid is a 32 bit positive integer created by the local pvmd.  The 32 bits are divided into fields that
       encode various information about this process such as its location in the  virtual  machine  (i.e.  local
       pvmd  address),  the  CPU  number  in the case where the process is on a multiprocessor, and a process ID
       field. This information is used by PVM and is not expected to  be  used  by  applications.   Applications
       should not attempt to predict or interpret the tid with the exception of calling tidtohost()

       If PVM has not been started before an application calls pvm_mytid the returned tid will be < 0.

EXAMPLES

       C:
            tid = pvm_mytid( );

       Fortran:
            CALL PVMFMYTID( TID )

ERRORS

       This error condition can be returned by pvm_mytid

       PvmSysErr
              pvmd not responding.
