SYNOPSIS
int msymbol_put (MSymbol symbol, MSymbol key, void * val)
DESCRIPTION
Set the value of a symbol property. The msymbol_put() function assigns val to the value of the symbol property that belongs to symbol and whose key is key. If the symbol property already has a value, val overwrites the old one. Both symbol and key must not be Mnil.If key is a managing key, val must be a managed object. In this case, the reference count of the old value, if not NULL, is decremented by one, and that of val is incremented by one.
RETURN VALUE
- If the operation was successful, msymbol_put() returns 0. Otherwise it returns -1 and assigns an error code to the external variable merror_code.
