NAME 
src/io/io_stdio.c - STDIO layer
DESCRIPTION
This is the Parrot IO STDIO layer. This may provide a subset of full functionality, but must compile on any system with the ANSI C standard library. Also note that unlike the other low-level IO layers (UNIX, Win32), this is buffered IO, out of necessity.
Functions
PARROT_CONST_FUNCTION PARROT_CANNOT_RETURN_NULL static const char *flags_to_stdio(INTVAL flags)- Returns a C string representation of
flagssuitable for passing tofopen()inPIO_stdio_open(). static INTVAL PIO_stdio_init(PARROT_INTERP, NOTNULL(ParrotIOLayer *layer))- Setup standard streams, etc.
PARROT_WARN_UNUSED_RESULT PARROT_CANNOT_RETURN_NULL static ParrotIO *PIO_stdio_open(PARROT_INTERP, SHIM(ParrotIOLayer *layer), NOTNULL(const char *spath), INTVAL flags)- Open modes (read,
write,
append,
etc.) are done in pseudo-Perl style using
<,>, etc. PARROT_WARN_UNUSED_RESULT PARROT_CANNOT_RETURN_NULL static ParrotIO *PIO_stdio_fdopen(PARROT_INTERP, SHIM(ParrotIOLayer *layer), PIOHANDLE fptr, INTVAL flags)- TODO: Not yet documented!!!
