PLAPACK provides platform independent level-2 BLAS calls by adding the prefix ``PLA_''. Thus the FORTRAN call
CALL DSYR2( "L", N, ALPHA, X, INCX, Y, INCY, A, LDA )becomes the C call
PLA_dsyr2( "L", &n, &alpha, x, &incx, y, &incy, a, &lda );Recall that only the first character of the string parameters are checked. Thus "L" is equivalent to "Lower triangular".
