OYJL_CREATE_VA_STRING

#define OYJL_CREATE_VA_STRING	(		format_,
			text_,
			alloc_,
			error_action
	)

Value:

if(format_ && strchr(format_,'%') != NULL) { \
  va_list list; \
  size_t sz = 0; \
  int len = 0; \
  void*(* allocate_)(size_t size) = alloc_; \
  if(!allocate_) allocate_ = malloc; \
\
  text_ = NULL; \
  \
  va_start( list, format_); \
  len = vsnprintf( text_, sz, format_, list); \
  va_end  ( list ); \
\
  { \
    text_ = (char*)allocate_( sizeof(char) * len + 2 ); \
    if(!text_) \
    { \
      oyjlMessage_p( oyjlMSG_ERROR, 0, OYJL_DBG_FORMAT "could not allocate memory", OYJL_DBG_ARGS ); \
      error_action; \
    } \
    va_start( list, format_); \
    len = vsnprintf( text_, len+1, format_, list); \
    va_end  ( list ); \
  } \
} else if(format_) \
{ \
  text_ = oyjlStringCopy( format_, alloc_ );\
}

convert ( const char * format, ... ) function args into a string
