[Pharo-project] NB How can I pass a NULL argument?

[Jan van de Sandt]

Hello list,

I want to call the following C function using NativeBoost:

const char* uenum_next(UEnumeration * en, int32_t * resultLength,
UErrorCode * status)

According to the (icu4c) documentation you can pass NULL for the
resultLenth argument [1]. But when I try:

self nbCall: #( char* uenum_next_48( self, nil, ICUErrorCodeNB* anErrorCode
) ) module: 'libicuuc.dylib'

My image craches. Does anyone know what I'm doing wrong?

Jan.
