The header file <cross_studio_io.h> defines functions that enable the target program to perform input and output using Virtual Console Services.

These functions are closely modelled on the standard C <stdio.h> functions.

Output functions
debug_printf Formatted output to the virtual console
debug_putchar Write one character to the virtual console
debug_puts Write string to the virtual console
Input functions
debug_getchar Read one character from the virtual console
debug_getd Read a double floating value from the virtual console
debug_getf Read a floating value from the virtual console
debug_geti Read an integer from the virtual console
debug_getl Read a long integer from the virtual console
debug_getll Read a long long integer from the virtual console
debug_gets Read a string from the virtual console
debug_getu Read an unsigned integer from the virtual console
debug_getul Read an unsigned long integer from the virtual console
debug_getull Read an unsigned long long integer from the virtual console
File functions
debug_fopen Open a file
debug_fflush Flush a file
debug_fclose Close a file
debug_fprintf Formatted output to a file
debug_fgetc Read one character from a file
debug_fgets Read a string from a file
debug_fputc Write one character to a file
debug_fputs Write a string to a file
debug_fread Read from a file
debug_fwrite Write to a file
debug_fseek Position a file
debug_ftell Remember position of a file
debug_rewind Reposition to start of a file
debug_filesize Get the size of a file
debug_clearerr Clear error flags associated with a file
debug_feof Test for end of file
debug_ferror Test a file for errors
Debug functions
debug_runtime_error Stop debugger and display a runtime error string
debug_break Programmed breakpoint that stops the debugger
Misc functions
debug_time Returns the number of seconds elapsed since midnight (00:00:00), January 1, 1970, coordinated universal time (UTC)
