I know there are caveats about using read in pipelines because read is treated by a subshell. I know this but I can't think of any way to accomplish this regardless, I'm still a rookie.
I hope somebody will be able to interpret what it is that I'm trying to accomplish and correct me.

tis_write_trylock
tis_write_trylock(3) Library Functions Manual tis_write_trylock(3)NAME
tis_write_trylock - Attempts to acquire the specified read-write lock for write access.
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <tis.h>
int tis_write_trylock(
tis_rwlock_t *lock);
STANDARDS
None
PARAMETERS
Address of the read-write lock to be acquired for write access.
DESCRIPTION
This routine attempts to acquire a read-write lock for write access. The routine attempts to immediately acquire the lock. If the lock is
acquired, zero (0) is returned. If the lock is held by another thread (for either read or write access), [EBUSY] is returned and the call-
ing thread does not wait for the write-access lock to be acquired.
Note that it is a coding error to attempt to acquire the lock for write access if the lock is already held by the calling thread. (However,
this routine returns [EBUSY] anyway, because no ownership error-checking takes place.)
RETURN VALUES
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:
Successful completion; the lock is acquired for write access. The lock was not acquired for write access, as it is already held by another
thread.
ERRORS
None
