Function pthread_barrierattr_init 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pthread_barrierattr_init(
    attr: *mut pthread_barrierattr_t,
) -> c_int

See https://pubs.opengroup.org/onlinepubs/9799919799/functions/pthread_barrierattr_init.html.

Initializes a barrier attributes object attr with the default value of all of the attributes defined by the implementation.

Upon success, returns 0. Upon error, returns an error number.

Implementation

Not async-signal-safe.

Safety

Undefined behaviour will occur if attr is already initialized.
