This feature is not supported on the Wolfram Cloud.

has been replaced by WSGetInteger32.

int MLGetInteger32(MLINK link,int *i)
gets a 32-bit integer from the MathLink connection specified by link and stores it in i.

DetailsDetails

  • If the data on the link corresponds to a real number, MLGetInteger32() will round it to an integer.
  • If the data on the link corresponds to an integer too large to store in a C int on your computer system, then MLGetInteger32() will fail, and return 0.
  • You can get arbitrary-precision integers by first using IntegerDigits to generate lists of digits, then calling MLGetInteger32List().
  • MLGetInteger32() returns a nonzero value if the function succeeds.
  • Use MLError() to retrieve the error code if MLGetInteger32() fails.
  • MLGetInteger32() is declared in the MathLink header file mathlink.h.
