Function Macro
GObjectVALUE_COLLECT
Declaration [src]
#define G_VALUE_COLLECT (
value,
var_args,
flags,
__error
)
Description [src]
Collects a variable argument value from a va_list
.
We have to implement the varargs collection as a macro, because on some systems
va_list
variables cannot be passed by reference.
Note: If you are creating the value
argument just before calling this macro,
you should use the G_VALUE_COLLECT_INIT() variant and pass the uninitialized
GValue
. That variant is faster than G_VALUE_COLLECT().
This function is not directly available to language bindings.
