Extracting permission of processes from the proc directory

I am trying to write a program in C where I have to print out the pid of processes in the proc directory that have read and write permissions. I've opened the proc directory and read the processes inside - I am only looking at the numeric directories. I know that I will have to open each numeric directory and open its maps file. How can I extract the permissions of each processes? The code below contains my attempt:
sprintf(buf, "/proc/%d/maps", tgid->d_name);
file = fopen(buf, "r");
while (fgets(buf, sizeof(buf), file))
sscanf(buf, "%x-%x %4c %x %x:%x %lu", &from, &to, flags, &offset, &major, &minor, &ino);
fclose(file);
if (flags[0] == 'r' && flags[1] == 'w')
printf("%dn", tgid->d_name);
