I wouldn't recommend the script in that post for a number of reasons.
For a start, it will fail on filenames containing spaces or other pathological characters.
It uses non-standard syntax that will not work in many POSIX shells.
It does not correctly read the entire line in some of the functions.
It uses a command that is no longer found on most systems (line).
It is an overwhelmingly large script for a person who needs to ask this question, and there are no useful comments to the functions.
The correct answer to the question is "use a while loop", as in this example:
There are, of course, variations on this, and for a large file, it is probably better to use sed or awk, depending on what needs to be done with the file.

semanage_seuser_iterate
semanage_iterate(3) Libsemanage API documentation semanage_iterate(3)NAME
semanage_iterate - SELinux Management API
SYNOPSIS
The following iterate function is supported for any semanage record.
Replace the function and object name as necessary.
extern int ITERATE_FUNCTION (
semanage_handle_t *handle,
int (*handler) (
const semanage_OBJECT_t *object,
void *varg),
void *handler_arg);
DESCRIPTION
Behavior:
The iterate function will execute the specified handler over all objects in the selected location. An arbitrary argument can be
passed into the handler function along with each object.
The object passed in is property of the libsemanage library, and may not be modified or preserved - use semanage_OBJECT_clone if
that is necessary.
The handler code may not invoke any semanage write requests for the same object type (i.e. modifying the underlying store is not
allowed). The iterate function is reentrant only while inside a transaction (see semanage_begin_transaction ). It is not safe to
execute other semanage read or write requests within iterate if not inside a transaction. The handler may return -1 to signal error
exit, 0 to signal continue, and 1 to signal successful exit early (the iterate function will stop accordingly).
Parameters:
The handle is used to track persistent state across semanage calls, and for error reporting. The handler is the function to execute,
with handler_arg as its second parameter, and each object as its first parameter.
Requirements:
This function requires an semanage connection to be established (see semanage_connect(3) )
RETURN VALUE
In case of failure, -1 is returned, and the semanage error callback is invoked, describing the error. Otherwise a non-negative integer is
returned (a commit number). The same number will be returned by all other semanage object read calls until the next commit.
