/*
*  Purpose
*  =======
*
*  PB_Cmalloc allocates a dynamic memory buffer. In case of failure, the
*  program is stopped by calling Cblacs_abort.
*
*  Arguments
*  =========
*
*  LENGTH  (local input) INTEGER
*          On entry, LENGTH  specifies the length in bytes of the buffer
*          to be allocated.  If LENGTH is less or equal than zero,  this
*          function returns NULL.
