xerbla_array.f(3) LAPACK xerbla_array.f(3)

xerbla_array.f -


subroutine xerbla_array (SRNAME_ARRAY, SRNAME_LEN, INFO)
 
XERBLA_ARRAY

XERBLA_ARRAY
Purpose:
 XERBLA_ARRAY assists other languages in calling XERBLA, the LAPACK
 and BLAS error handler.  Rather than taking a Fortran string argument
 as the function's name, XERBLA_ARRAY takes an array of single
 characters along with the array's length.  XERBLA_ARRAY then copies
 up to 32 characters of that array into a Fortran string and passes
 that to XERBLA.  If called with a non-positive SRNAME_LEN,
 XERBLA_ARRAY will call XERBLA with a string of all blank characters.
Say some macro or other device makes XERBLA_ARRAY available to C99 by a name lapack_xerbla and with a common Fortran calling convention. Then a C99 program could invoke XERBLA via: { int flen = strlen(__func__); lapack_xerbla(__func__, &flen, &info); }
Providing XERBLA_ARRAY is not necessary for intercepting LAPACK errors. XERBLA_ARRAY calls XERBLA.
Parameters:
SRNAME_ARRAY
          SRNAME_ARRAY is CHARACTER(1) array, dimension (SRNAME_LEN)
          The name of the routine which called XERBLA_ARRAY.
SRNAME_LEN
          SRNAME_LEN is INTEGER
          The length of the name in SRNAME_ARRAY.
INFO
          INFO is INTEGER
          The position of the invalid parameter in the parameter list
          of the calling routine.
