3. Application Programming Interface

SMPlib APIs for both C and Fortran languages are listed in this section. The Fortran interface has a very similar syntax as the C interface except for the memory allocation routines, such as SMP_GETSHMEM and SMP_GETLOCMEM. SMP_GETSHMEMP is added for a platform that supports the Cray pointer. So, in most cases both C and Fortran interfaces are described togather. For those routines error conditions may exist, the corresponding error codes are included; otherwise, no error will be generated. A list of error codes is given in Section 5.
