/*
*  Purpose
*  =======
*
*  PB_Cabort is an error handler for the PBLAS  routines.  This  routine
*  displays an error message on  stderr  by calling  PB_Cwarn, and halts
*  execution by calling Cblacs_abort().
*
*  Arguments
*  =========
*
*  ICTXT   (local input) INTEGER
*          On entry,  ICTXT  specifies the BLACS context handle, indica-
*          ting the global  context of the operation. The context itself
*          is global, but the value of ICTXT is local.
*
*  ROUT    (global input) pointer to CHAR
*          On entry, ROUT specifies the name of the routine calling this
*          error handler.
*
*  INFO    (local input) INTEGER
*          The error code computed by the calling PBLAS routine.
*          = 0:  no error found
*          < 0:  If the  i-th  argument is an array and the j-entry  had
*                an illegal value, then  INFO = -(i*100+j),  if the i-th
*                argument  is  a  scalar  and had an illegal value, then
*                INFO = -i.
