C64 Language Reference
C64 Language Reference C64 supports an extended ‘C’ language compiler. In addition to the standard ‘C’ language C64 adds the following: run-time type identification (via typenum()) exception handling (via try/throw/catch) spinlocks (via spinlock/lockfail/spinunlock) interrupt functions multiple case constants eg. case ‘1’,’2’,’3’: inline assembler code (asm) pascal calling conventions (pascal) no calling conventions (nocall / naked) additional loop constructs (until, loop, forever) true/false are defined as 1 and 0 respectively thread storage class The following additions have been made: typenum(<type>) allow run-time type identification. It returns a hash code for the type specified. It works the same way the sizeof() operator works, but it returns a code for the type, rather than the types size. C64 supports a simple try/throw/catch mechanism. A catch statement without a variable declaration catches all exceptions. try { <statement> } catch(var decl) { } catch(var decl) { } catch { } Types: A byte is one byte (8 bits) in size. A char is two bytes (16 bits) in size. An int is eight bytes (64 bits) wide. An short int is four bytes (32 bits) wide Pointers are eight bytes (64 bits) wide. typenum() Typenum() works like the sizeof() operator, but it returns a hashcode representing the type, rather than the size of the type. Typenum() can be used to identify types at run-time. struct tag { int i; }; main() { int n; n = typenum(struct tag); } spinlock A spinlock acts to guard a section of program code against re-entry. The spinlock will block a second thread from executing a protected section of code, until the first thread is finished with it. -
