int MLGetReal32(MLINK link, float *x)
gets a single-precision floating-point number from link and stores it as a float in x.


  • MLGetReal32() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use MLError() to retrieve the error code if MLGetReal32() fails.
  • MLGetReal32() is declared in the MathLink header file mathlink.h.
