 *  -- V1.1 BLACS routine --
 *  University of Tennessee, May 1, 1996

 *
 *  Purpose
 *  =======
 *  Globally-blocking point to point general integer receive.
 *
 *  Arguments
 *  =========
 *
 *  ConTxt  (input) Ptr to int
 *          Index into MyConTxts00 (my contexts array).
 *
 *  M       (input) Ptr to int
 *          The number of rows of the matrix A.  M >= 0.
 *
 *  N       (input) Ptr to int
 *          The number of columns of the matrix A.  N >= 0.
 *
 *  A       (output) Ptr to integer two dimensional array
 *          The m by n matrix A.  Fortran77 (column-major) storage
 *          assumed.
 *
 *  LDA     (input) Ptr to int
 *          The leading dimension of the array A.  LDA >= M.
 *
 *
 *  RSRC    (input) Ptr to int
 *          The process row of the source of the matrix.
 *
 *  CSRC    (input) Ptr to int
 *          The process column of the source of the matrix.
