If they’re reading tab separated files, I wouldn’t use CSV code... there’s a
lot of complexity in CSV readers that are unnecessary for TSV because it
doesn’t support or require quoting of embedded separators.
Just something like
char *s, *cols[MAXLINE], line[MAXLINE];
int col;
while(fgets(line, MAXLINE, fp)) {
s = line;
col = 0;
while(cols[col] = s, s = strchr(s, ‘\t’)) {
*s++ = ‘\0’;
col++;
}
if(s = strchr(cols[col], ‘\n’)) *s = ‘\0’;
// bind cols[...] to prepared statement
// step prepared statement
}
