| This header can be included into both Fortran and C. |
| |
| This file defines various code values that need to be exported |
| to predefined Fortran standard modules as well as to C/C++ |
| code in the compiler and runtime library. |
| These include: |
| - the error/end code values that can be returned |
| to an IOSTAT= or STAT= specifier on a Fortran I/O statement |
| or coindexed data reference (see Fortran 2018 12.11.5, |
| 16.10.2, and 16.10.2.33) |
| Codes from <errno.h>, e.g. ENOENT, are assumed to be positive |
| and are used "raw" as IOSTAT values. |
| |
| CFI_ERROR_xxx and CFI_INVALID_xxx macros from ISO_Fortran_binding.h |
| have small positive values. The FORTRAN_RUNTIME_STAT_xxx macros here |
| start at 100 so as to never conflict with those codes. |
