pthread_attr_init_destroy(3) [osx man page]

PTHREAD_ATTR(3) 					   BSD Library Functions Manual 					   PTHREAD_ATTR(3)

NAME

     pthread_attr_destroy, pthread_attr_init -- thread attribute operations

SYNOPSIS

     #include <pthread.h>

     int
     pthread_attr_destroy(pthread_attr_t *attr);

     int
     pthread_attr_init(pthread_attr_t *attr);

DESCRIPTION

     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     The pthread_attr_init() function initializes attr with all the default thread attributes.

     The pthread_attr_destroy() function destroys attr.

RETURN VALUES

     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.

ERRORS

     pthread_attr_init() will fail if:

     [ENOMEM]		Out of memory.

     pthread_attr_destroy() will fail if:

     [EINVAL]		Invalid value for attr.

SEE ALSO

     pthread_create(3)

STANDARDS

     pthread_attr_init(), pthread_attr_destroy() conform to ISO/IEC 9945-1:1996 (``POSIX.1'')

DESCRIPTION

     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     The pthread_attr_init() function initializes attr with all the default thread attributes.

     The pthread_attr_destroy() function destroys attr.

     The pthread_attr_set*() functions set the attribute that corresponds to each function name.

     The pthread_attr_get*() functions copy the value of the attribute that corresponds to each function name to the location pointed to by the
     second function parameter.

RETURN VALUES

     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.

ERRORS

     The pthread_attr_init() function will fail if:

     [ENOMEM]		Out of memory.

     The pthread_attr_destroy() function will fail if:

     [EINVAL]		Invalid value for attr.
