Rather than taking a Fortran string argument 00038 *> as the function's name, XERBLA_ARRAY takes an array of single 00039 *> characters along with the array's length. XERBLA_ARRAY then copies 00040 *> up to 32 characters of that array into a Fortran string and passes 00041 *> that to XERBLA. If called with a non-positive SRNAME_LEN, 00042 *> XERBLA_ARRAY will call XERBLA with a string of all blank characters. 00043 *> 00044 *> Say some macro or other device makes XERBLA_ARRAY available to C99 00045 *> by a name lapack_xerbla and with a common Fortran calling convention. 00046 *> Then a C99 program could invoke XERBLA via: 00047 *> { 00048 *> int flen = strlen(__func__); 00049 *> lapack_xerbla(__func__, &flen, &info); 00050 *> } 00051 *> 00052 *> Providing XERBLA_ARRAY is not necessary for intercepting LAPACK 00053 *> errors. XERBLA_ARRAY calls XERBLA. 00054 *> \endverbatim 00055 * 00056 * Arguments: 00057 * ========== 00058 * 00059 *> \param[in] SRNAME_ARRAY 00060 *> \verbatim 00061 *> SRNAME_ARRAY is CHARACTER(1) array, dimension (SRNAME_LEN) 00062 *> The name of the routine which called XERBLA_ARRAY. 00063 *> \endverbatim 00064 *> 00065 *> \param[in] SRNAME_LEN 00066 *> \verbatim 00067 *> SRNAME_LEN is INTEGER 00068 *> The length of the name in SRNAME_ARRAY. 00069 *> \endverbatim 00070 *> 00071 *> \param[in] INFO 00072 *> \verbatim 00073 *> INFO is INTEGER 00074 *> The position of the invalid parameter in the parameter list 00075 *> of the calling routine. 00076 *> \endverbatim 00077 * 00078 * Authors: 00079 * ======== 00080 * 00081 *> \author Univ. of Tennessee 00082 *> \author Univ. of California Berkeley 00083 *> \author Univ. of Colorado Denver 00084 *> \author NAG Ltd. 00085 * 00086 *> \date November 2011 00087 * 00088 *> \ingroup auxOTHERauxiliary 00089 * 00090 * ===================================================================== 00091 SUBROUTINE XERBLA_ARRAY( SRNAME_ARRAY, SRNAME_LEN, INFO) 00092 * 00093 * -- LAPACK auxiliary routine (version 3.4.0) -- 00094 * -- LAPACK is a software package provided by Univ. of Tennessee, -- 00095 * -- Univ. of California Berkeley, Univ. of Colorado Denver and NAG Ltd..-- 00096 * November 2011 00097 * 00098 * ..
