Anyone know how to use the seek() function of Arduino SD Library to position pointer at the end of a file?
If programming in Windows do something like:
void fileInsert(char *file, void *data, size_t len) {
FILE *filePtr;
if ((filePtr = fopen(file, "rb+")) == NULL) {
printf("Arquivo %s não pode ser aberto.", file);
exit(EPERM);
} else {
fseek(filePtr, 0L, SEEK_END);
fwrite(data, len, 1, filePtr);
fclose(filePtr);
}
}
But the Arduino does not have the SEEK_END
