Macro Functions

spvm_warn

#define spvm_warn(format, ...)

Prints the formatted message format to stderr with a new line.

format must be the char* type.

Examples:

spvm_warn("Hello");
spvm_warn("Hello %s%d", "Foo", 3);

spvm_warnf

#define spvm_warnf(stream, format, ...)

Prints the formatted message format to the stream stream with a new line.

format must be the char* type.

stream must be the FILE type.

Examples:

spvm_warnf(env->spvm_stderr(env, stack), "Hello");
spvm_warnf(env->spvm_stderr(env, stack), "Hello %s%d", "Foo", 3);

SPVM_NATIVE_GET_POINTER

#define SPVM_NATIVE_GET_POINTER(object)

Returns the pointer stored in the object object and returns it. The return type is the void* type.
