NAME

classes/parrotio.pmc - Parrot IO

DESCRIPTION

These are the vtable functions for Parrot IO.

METHOD INTVAL say(STRING *s): Print the string with newline appended to SELF or to stdout if used as class method
METHOD PMC *open(STRING *file, STRING *mode, STRING *layer): Open the file with the given mode and use the IO given layer.
void class_init(): Class initialization.
METHOD INTVAL eof(): Return 0/1 according to eof state of the object.
METHOD void flush(): Flush pending writes.
METHOD INTVAL setbuf(INTVAL): XXX TBD
METHOD INTVAL setlinebuf(): XXX TBD
void init(): Initializes the IO PMC.
void destroy(): Destroys the IO PMC, flushing and closing as necessary.
PMC *clone(): Clones the IO PMC.; For now both PMCs refer to the same ParrotIO object. If we have different IO layers, we might copy data and struct_val.
INTVAL get_bool(): Returns whether at EOF or not.
STRING *get_string_keyed_int(INTVAL n): Return the name of the nth layer. n >= 0 returns layer names up from the bottom. If n is negative returns layer names from top down. For non-existing layers an empty string is returned.
void push_string (STRING *value): Push the layer name value onto the PIO's layer stack.
STRING *pop_string (): Pop a layer off the PIO's layer stack. Returns the layer name.
