Synopsis
int getunvalue(XPRMcontext ctx, XPRMunion un, XPRMalltypes *value);
Arguments
ctx

un 
Reference to a union entity
value 
Pointer to an area where the value is returned
Return value
An encoded type, 0 if the union is undefined or -1 in case of error.
Further information
The returned type information is either a type ID (see getuntypeid) or a structure code ( XPRM_STR_ARR, XPRM_STR_SET or XPRM_STR_LIST). In the case of a reference to a non basic type it will be necessary to check the type properties with gettypeprop in order to identify a structured type.
