78 <h2 class="chapter">7 Calling FFTW from Modern Fortran</h2> | |
79 <a name="index-Fortran-interface-2"></a> | |
80 | |
81 <p>Fortran 2003 standardized ways for Fortran code to call C libraries, | |
82 and this allows us to support a direct translation of the FFTW C API | |
83 into Fortran. Compared to the legacy Fortran 77 interface | |
84 (see <a href="Calling-FFTW-from-Legacy-Fortran.html#Calling-FFTW-from-Legacy-Fortran">Calling FFTW from Legacy Fortran</a>), this direct interface | |
85 offers many advantages, especially compile-time type-checking and | |
86 aligned memory allocation. As of this writing, support for these C | |
87 interoperability features seems widespread, having been implemented in | |
88 nearly all major Fortran compilers (e.g. GNU, Intel, IBM, | |
89 Oracle/Solaris, Portland Group, NAG). | |
90 <a name="index-portability-4"></a> | |
91 </p> | |
92 <p>This chapter documents that interface. For the most part, since this | |
93 interface allows Fortran to call the C interface directly, the usage | |
94 is identical to C translated to Fortran syntax. However, there are a | |
95 few subtle points such as memory allocation, wisdom, and data types | |
96 that deserve closer attention. | |
