Array Descriptor Library

Fortran 90 (and later) compilers pass array-valued parameters via an array descriptor (sometimes called a dope vector). The Chasm library provides C functions to access elements in an array descriptor.

The API for the array descriptor library is divided into several groups:

• Creation and initialization of an array descriptor:
  1. createArrayDesc_F90Vendor()
  2. setArrayDesc_F90Vendor()
  3. resetArrayDesc_F90Vendor()
• Creation and initialization of a temporary, array and hidden descriptor pair, used in a procedure call:
  1. copyToArrayDescAndHidden_F90Vendor()
  2. createArrayDescAndHidden_F90Vendor()
  3. freeArrayDescAndHidden_F90Vendor()
• Access functions:
  1. getArrayBaseAddress_F90Vendor()
  2. getArraySize_F90Vendor()
  3. getArrayLowerBound_F90Vendor()
  4. getArrayExtent_F90Vendor()
  5. getArrayStrideMult_F90Vendor()
• Miscellaneous helper functions:
  1. getArrayDescSize_F90Vendor()
  2. hiddenArrayDescType_F90Vendor()
  3. verifyArrayDesc_F90Vendor()
  4. nullifyArrayDesc_F90Vendor()
  5. printArrayDesc_F90Vendor()
  6. equalsArrayDesc_F90Vendor()
  7. getMangledName_F90Vendor()
  8. F90_SetCCFunctions_F90Vendor()
