I provide access to actual machine addresses of OOPs and objects. I
have no instances; you send messages to my class to map between an object
and the address of its OOP or object. In addition I provide direct
memory access with different C types (ints, chars, OOPs, floats,...).
Access the Smalltalk object (OOP) at the given address.
at: anAddress put: aValue
Store a pointer (OOP) to the Smalltalk object identified by `value'
at the given address.
bigEndian
Answer whether we're running on a big- or little-endian system.
charAt: anAddress
Access the C char at the given address. The value is
returned as a Smalltalk Character.
charAt: anAddress put: aValue
Store as a C char the Smalltalk Character or Integer object
identified by `value', at the given address, using sizeof(char)
bytes - i.e. 1 byte.
deref: anAddress
Access the C int pointed by the given address
doubleAt: anAddress
Access the C double at the given address.
doubleAt: anAddress put: aValue
Store the Smalltalk Float object identified by `value', at the
given address, writing it like a C double.
floatAt: anAddress
Access the C float at the given address.
floatAt: anAddress put: aValue
Store the Smalltalk Float object identified by `value', at the
given address, writing it like a C float.
intAt: anAddress
Access the C int at the given address.
intAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(int) bytes.
longAt: anAddress
Access the C long int at the given address.
longAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(long) bytes.
longDoubleAt: anAddress
Access the C long double at the given address.
longDoubleAt: anAddress put: aValue
Store the Smalltalk Float object identified by `value', at the
given address, writing it like a C long double.
shortAt: anAddress
Access the C short int at the given address.
shortAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(short) bytes.
stringAt: anAddress
Access the string pointed by the C `char *' at the given given address.
stringAt: anAddress put: aValue
Store the Smalltalk String object identified by `value', at the
given address in memory, writing it like a *FRESHLY ALLOCATED*
C string. It is the caller's responsibility to free it if
necessary.
ucharAt: anAddress put: aValue
Store as a C char the Smalltalk Character or Integer object
identified by `value', at the given address, using sizeof(char)
bytes - i.e. 1 byte.
uintAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(int) bytes.
ulongAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(long) bytes.
unsignedCharAt: anAddress
Access the C unsigned char at the given address.
The value is returned as a Smalltalk Character.
unsignedCharAt: anAddress put: aValue
Store as a C char the Smalltalk Character or Integer object
identified by `value', at the given address, using sizeof(char)
bytes - i.e. 1 byte.
unsignedIntAt: anAddress
Access the C unsigned int at the given address.
unsignedIntAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(int) bytes.
unsignedLongAt: anAddress
Access the C unsigned long int at the given address.
unsignedLongAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(long) bytes.
unsignedShortAt: anAddress
Access the C unsigned short int at the given address.
unsignedShortAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(short) bytes.
ushortAt: anAddress put: aValue
Store the Smalltalk Integer object identified by `value', at the
given address, using sizeof(short) bytes.
