Passing FILE* as parameter

Question

I know this is a common question but answers are varying a lot depending on context and not only have the found contexts been way simpler but also the found solutions haven't worked so far.

char* loadText(FILE** f, char* text){
    int nbytes, bufferSize = BUFFERSIZE;
    char* buff = (char*) malloc(sizeof(char) * bufferSize);
    while(1){
        nbytes = fread(buff, sizeof(char), bufferSize, *f);
        if(nbytes == bufferSize){
            bufferSize *= 2;
            buff = (char*) malloc(sizeof(char) * bufferSize);
        }
        else break;
    }
    text = buff;
    return text;
}

int main(){
    FILE* f = fopen("sometextfile.txt", "read");
    char* text;
    text = loadText(&f, text);
    fclose(f);
    printf("%s", text);
    return 0;
}

There is no output. I've also tried with loadText(File* f, char* text). Same results. What am I doing wrong?

char* loadText(FILE* f, char **text)
{
    size_t nbytes = 0, bufferSize = BUFFERSIZE;
    char* buff = malloc(bufferSize);
    if(!buff){/*error handling*/}
    while(1){
        nbytes += fread(buff + nbytes, 1, bufferSize - nbytes, f);
        if(nbytes == bufferSize)
        {
            char *tmp;
            bufferSize *= 2;
            tmp = realloc(buff, bufferSize);
            if(tmp) buff = tmp;
            else {/*error handling*/}
        }
        else break;
    }
    *text = buff;
    return *text;
}
