SYNOPSIS

          #include <pmix.h>

          pmix_status_t PMIx_Abort(int status, const char msg[],
                                   pmix_proc_t procs[], size_t nprocs);

ARGUMENTS

       • status:  Status  value to be returned. A value of zero is permitted by PMIx, but may not be returned by
         some resource managers.

       • msg: A string message to be displayed.

       • procs: An array of pmix_proc_t structures defining the processes to be aborted. A  NULL  for  the  proc
         array  indicates  that  all processes in the caller’s namespace are to be aborted. A wildcard value for
         the rank in any structure indicates that all processes in that namespace are to be aborted.

       • nprocs: Number of pmix_proc_t structures in the procs array.

DESCRIPTION

       Request that the provided array of procs be aborted, returning  the  provided  status  and  printing  the
       provided  message.  A NULL for the procs array indicates that all processes in the caller’s namespace are
       to be aborted.

       The response to this request is somewhat dependent on the specific resource manager and its configuration
       (e.g., some resource managers will not abort the application  if  the  provided  status  is  zero  unless
       specifically  configured to do so), and thus lies outside the control of PMIx itself. However, the client
       will inform the RM of the request that the application  be  aborted,  regardless  of  the  value  of  the
       provided status.

       Passing  a  NULL msg parameter is allowed. Note that race conditions caused by multiple processes calling
       PMIx_Abort are left to the server implementation to resolve with regard to which status is  returned  and
       what messages (if any) are printed.

RETURN VALUE

       Returns PMIX_SUCCESS on success. On error, a negative value corresponding to a PMIx errno is returned.

ERRORS

       PMIx errno values are defined in pmix_common.h.
