pthread_attr_getname_np, pthread_attr_setname_np — get and set descriptive name of an attribute

POSIX Threads Library (libpthread, -lpthread)

#include <pthread.h>

int
pthread_attr_getname_np(const pthread_attr_t attr, char *name, size_t len);

int
pthread_attr_setname_np(pthread_attr_t attr, const char *name, void *arg);

The () function gets the descriptive name of a thread attribute. It takes the following arguments:

attr
The attribute whose descriptive name will be obtained.
name
The buffer to be filled with the descriptive name of the attribute.
len

The () function sets the descriptive name of a thread attribute. It takes the following arguments:

attr
The attribute whose descriptive name will be set.
name
The printf(3) format string to be used to construct the descriptive name of the attribute. The resulted descriptive name should be shorter than PTHREAD_MAX_NAMELEN_NP.
arg
The printf(3) argument used with name.

Both functions return 0 on success. Otherwise, an error number is returned.

Both functions are non-standard extensions.

No errors are defined for pthread_attr_getname_np().

The pthread_attr_setname_np() function may fail if:

[]
The supplied descriptive name was longer than PTHREAD_MAX_NAMELEN_NP.
[]
There was insufficient memory for the operation.
