MathLink C Function

MLGetInteger32Array()

int MLGetInteger32Array(MLINK link, int **a, int **dims, char ***heads, int *d)
gets an array of 32-bit integers from the MathLink connection specified by link, storing the array in a, its dimensions in dims and its depth in d.
  • The array a is laid out in memory like a C array declared as int a[m][n]....
  • heads gives a list of character strings corresponding to the names of symbols that appear as heads at each level in the array.
  • MLGetInteger32Array() allocates memory which must be disowned by calling MLReleaseInteger32Array(). If MLGetInteger32Array() fails and the function's return value indicates an error, do not call MLReleaseInteger32Array() on the contents of a.
  • MLGetInteger32Array() returns immutable data.
  • MLGetInteger32Array() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use MLError() to retrieve the error code if MLGetInteger32Array() fails.
  • MLGetInteger32Array() is declared in the MathLink header file mathlink.h.
