Passing C string array to Fortran

[Martin__Paul]

I am calling a 3rd party Fortran DLL from C. The manual describes a function whose arguments are

integer nunits,ierr
character units(*)*(*)
units (in) list of units
nunits (in) number of units
ierr (out) error flag

In C I am declaring the arguments to the function as follows:

int nunits = 2;

int iFail = 0;

char** myCache = new char*[3];
myCache[0] = "S1";
myCache[1] = "S2";

The function call is thus:

SetUnits(myCache, &nunits, &iFail);

but this results in an access violation.

I think it's likely to have to do with the string array. What is the C equivalent of (*)*(*)?

Thanks in adv.

I tried passing separate string arguments in for character units(*)*(*) and it worked.

If you talk about the "C equivalent" of Fortran strings, you should be considering iso_c_binding. This supports interoperability with an array of C_CHAR.
