Feature

Support File I/O in C++ and C

It allows you to read files in gbfs with C standard library functions and C++ fstream.

int fd = open("xxx.txt", O_RDONLY);
read(fd, dest, size);

int i, j;
FILE *fp = fopen("xxx.txt", "r");
fscanf(fp, "%d %d", &i, &j);

std::ifstream fs("xxx.txt");
std::stringstream ss;
ss << fs.rdbuf();

Special filenames preserved for that:

• sram:

• sram_512Kb:
• eeprom:
• eeprom_512B:
• eeprom_4Kb:
• eeprom_8KB:
• eeprom_64Kb:

FILE *fp = fopen("sram:", "r+");

int fd = open("eeprom:", O_RDWR);
FILE *fp = fopen("eeprom:", "r+");
