Error Handling

On success, S3L_to_ScaLAPACK_desc returns S3L_SUCCESS.

S3L_to_ScaLAPACK_desc performs generic checking of the validity of the arrays it accepts as arguments. If an array argument contains an invalid or corrupted value, the function terminates and an error code indicating which value of the array handle was invalid is returned. See Appendix A of this manual for a detailed list of these error codes.

In addition, the following conditions will cause the function to terminate and return the associated error code:

• S3L_ERR_ARG_NULL - The s3ldesc argument is a NULL pointer (C/C++) or 0 (F77/F90).

• S3L_ERR_ARG_RANK - The S3L array handle refers to an array with a rank not equal to 2.

• S3L_ERR_PGRID_NOPROCS - The ScaLAPACK descriptor has an invalid BLACS context.
