(*((_SINGARR) _receptive->__m2dimensio   g_curr  )) = (_SINGARR) malloc(sizeof(*((_SINGARR)(_generic)) * g));

the aforementioned produces the following compiler warning "assignment makes integer from pointer without a cast "

I suppose it's somehow procured by the sizeof operator evaluation of the typecasted dereferenced void* or am I just not dereferencing accordingly?

_generic is a void* method parameter

_receptive - typedef struct* method parameter used in the accessing of its 2D-array property (also pseudo-generic)

expanded directives

_SINGARR char*

CodePudding user response：

When you expand all the stuff, it looks like

* (char*) p = (char*) malloc(...);

This means, there is a pointer on the right side (char*) and a character (*(char*), integer type) on the left side.

Now the warning message becomes clearer:

assignment makes integer (the part on the left side of the assignment) from pointer (the part on the right side of the assignment) without a cast

Unrelated, but expanding the sizeof(...) part will become sizeof(*((char*)(_generic)) * g), which in turn is sizeof(<some character value> * g), which in turn will become sizeof(<some integer value>), which is sizeof(int) and finally becomes 4 or 8 bytes depending on the architecture of your machine.
