◆ mxvm_string_inttostr()

void mxvm_string_inttostr	(	mxvm::Program *	program,
		std::vector< mxvm::Operand > &	operand )

Convert an integer to its decimal string representation.

Allocates a new heap buffer for the result string and returns it via rax as a pointer. Frees any previously-owned pointer in rax before overwriting to prevent memory leaks from repeated calls (e.g. inttostr(score) inside a render loop).

Parameters

program	VM program context.
operand	Single operand: the integer variable to convert.
