inside [] or [[]] use -gt/-eq/-lt/etc... [[]] might be safe because it's built into the shell but you should use the proper operators.
inside (()) values will be treated as numeric. see also let
also - please use CODE tags around the logic.

pthread_condattr_init
PTHREAD_CONDATTR(3) Library Functions Manual PTHREAD_CONDATTR(3)
NAME
pthread_condattr_init, pthread_condattr_destroy - condition creation attributes
SYNOPSIS
#include <pthread.h>
int pthread_condattr_init(pthread_condattr_t *attr);
int pthread_condattr_destroy(pthread_condattr_t *attr);
DESCRIPTION
Condition attributes can be specified at condition creation time, by passing a condition attribute object as second argument to
pthread_cond_init(3). Passing NULL is equivalent to passing a condition attribute object with all attributes set to their default values.
The LinuxThreads implementation supports no attributes for conditions. The functions on condition attributes are included only for compli-
ance with the POSIX standard.
pthread_condattr_init initializes the condition attribute object attr and fills it with default values for the attributes. pthread_con-
dattr_destroy destroys a condition attribute object, which must not be reused until it is reinitialized. Both functions do nothing in the
LinuxThreads implementation.
RETURN VALUE
pthread_condattr_init and pthread_condattr_destroy always return 0.
