pthread_condattr_init()

Initialize condition variable attribute object

Synopsis:

#include <pthread.h>

int pthread_condattr_init( pthread_condattr_t* attr );

Library:

libc

Description:

The pthread_condattr_init() function initializes the attributes in the condition variable attribute object attr to default values. When attr is passed to the pthread_cond_init() function, it defines the attributes of the condition variable.

Condition variables have at least the following attributes defined:

PTHREAD_PROCESS_PRIVATE

The condition variable can only be accessed by threads created within the same process as the thread that initialized the condition variable.

PTHREAD_PROCESS_SHARED

Any thread that has access to the memory where the condition variable is allocated can access the condition variable.

For more information about these attributes, see pthread_condattr_getpshared() and pthread_condattr_setpshared().

Returns:

EOK

Success.

ENOMEM

Insufficient memory to initialize the condition variable attribute object attr.
