Distribution means a certain set of applications that are bundled and pre-configured. The difference in that for Linux distributions (or distros) can range from almost nothing (eg. RHEL vs. CentOS), to a completely different intention, and thus software selection (eg. Slackware vs. Mint)
Different "flavours" are called that because they are based on the same principles (POSIX, Single UNIX Specification), but follow different ways for implementation. For example, while all Unices have a sigaction system call, probably none of them share the same implementation, as the Kernel itself follows different specifications.
I hope I helped clear some of the confusion.

pthread_setconcurrency
PTHREAD_GETCONCURRENCY(3) BSD Library Functions Manual PTHREAD_GETCONCURRENCY(3)
NAME
pthread_getconcurrency, pthread_setconcurrency -- get or set level of concurrency
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
int
pthread_getconcurrency(void);
int
pthread_setconcurrency(int new_level);
DESCRIPTION
The pthread_setconcurrency() function allows an application to inform the threads implementation of its desired concurrency level, new_level.
The actual level of concurrency provided by the implementation as a result of this function call is unspecified. If new_level is zero, it
causes the implementation to maintain the concurrency level at its discretion as if pthread_setconcurrency() was never called. The
pthread_getconcurrency() function returns the value set by a previous call to the pthread_setconcurrency() function. If the
pthread_setconcurrency() function was not previously called, this function returns zero to indicate that the implementation is maintaining
the concurrency level. When an application calls pthread_setconcurrency(), it is informing the implementation of its desired concurrency
level. The implementation uses this as a hint, not a requirement.
RETURN VALUES
If successful, the pthread_setconcurrency() function returns zero. Otherwise, an error number is returned to indicate the error. The
pthread_getconcurrency() function always returns the concurrency level set by a previous call to pthread_setconcurrency(). If the
pthread_setconcurrency() function has never been called, pthread_getconcurrency() returns zero.
ERRORS
The pthread_setconcurrency() function will fail if:
[EINVAL] The value specified by new_level is negative.
[EAGAIN] The value specified by new_level would cause a system resource to be exceeded.
APPLICATION USAGE
Use of these functions changes the state of the underlying concurrency upon which the application depends. Library developers are advised to
not use the pthread_getconcurrency() and pthread_setconcurrency() functions since their use may conflict with an application's use of these
functions.
STANDARDS
The pthread_getconcurrency() and pthread_setconcurrency() functions conform to Version 2 of the Single UNIX Specification (``SUSv2'').
