c++ - When to use pthread_mutex_t -

can please explain in scenario's beneficial use std::mutex vs pthread_mutex_t. dont understand why ever use pthread_mutex_t. thanks

std::mutex thin wrapper around pthread_mutex on systems supporting pthreads.

in general, operations on std:: thread primitives quite limited vs native versions (pthreads or windows threads). if don't need features, should use std:: versions, if need advanced features, have no choice use native version.
