Gets the mutex attribute pshared, priority ceiling, protocol, and type values.

#include <sys/pthdebug.h>int pthdb_mutexattr_addr (pthdb_session_t session,
pthdb_mutexattr_t mutexattr,

The pthdb_mutexattr_addr function reports the address of the pthread_mutexatt_t.
The pthdb_mutexattr_prioceiling function is used to get the mutex attribute priority ceiling value.
The pthdb_mutexattr_protocol function is used to get the mutex attribute protocol value. The protocol value can be MP_INHERIT, MP_PROTECT, MP_NONE, or MP_NOTSUP.
The pthdb_mutexattr_pshared function is used to get the mutex attribute process shared value. The pshared value can be PSH_SHARED, PSH_PRIVATE, or PSH_NOTSUP.
The pthdb_mutexattr_type is used to get the value of the mutex attribute type. The values for the mutex type can be MK_NONRECURSIVE_NP, MK_RECURSIVE_NP, MK_FAST_NP, MK_ERRORCHECK, MK_RECURSIVE, MK_NORMAL, or MK_NOTSUP.
| Item | Description |
|---|---|
| addr | Mutex attribute address. |
| mutexattr | Condition variable attribute handle |
| prioceiling | Pointer to priority ceiling value. |
| protocolp | Pointer to protocol value. |
| psharedp | Pointer to pshared value. |
