C read file line by line

Question

I wrote this function to read a line from a file:

const char *readLine(FILE *file) {

    if (file == NULL) {
        printf(\"Error: file pointer is null.\"         


        

Answer 1

void readLine(FILE* file, char* line, int limit)
{
    int i;
    int read;

    read = fread(line, sizeof(char), limit, file);
    line[read] = '\0';

    for(i = 0; i <= read;i++)
    {
        if('\0' == line[i] || '\n' == line[i] || '\r' == line[i])
        {
            line[i] = '\0';
            break;
        }
    }

    if(i != read)
    {
        fseek(file, i - read + 1, SEEK_CUR);
    }
}

what about this one?
