One-time execution(3) globus common One-time execution(3)
NAME
One-time execution -
Data Structures
union globus_thread_once_t
Thread once structure.
Macros
#define GLOBUS_THREAD_ONCE_INIT { .none = 0 }
Functions
int globus_thread_once (globus_thread_once_t *once, void(*init_routine)(void))
Detailed Description
The globus_thread_once_t provides a way for applications and libraries to execute some code exactly one time, independent of the number of
threads which attempt to execute it. To use this, statically initialize a globus_thread_once_t control with the value
GLOBUS_THREAD_ONCE_INIT, and pass a pointer to a function to execute once, along with the control, to globus_thread_once().
Macro Definition Documentation
#define GLOBUS_THREAD_ONCE_INIT { .none = 0 }
Thread once initializer value.
Function Documentation
int globus_thread_once (globus_thread_once_t *once, void(*)(void)init_routine)
Execute a function one time. .PP
The globus_thread_once() function will execute the function pointed to
by its @a init_routine parameter one time for each unique
globus_thread_once_t object passed to it, independent of the number
of threads calling it. The @a once value must be a static value
initialized to GLOBUS_THREAD_ONCE_INIT.
Parameters:
once A pointer to the value used to govern whether the function passed via the init_routine parameter has executed.
init_routine Function to execute one time. It is called with no parameters.
Returns:
On success, globus_thread_once() guarantees that the function pointed to by init_routine has run, and that subsequent calls to
globus_thread_once() with the same value of once will not execute that function, and returns GLOBUS_SUCCESS. If an error occurs,
globus_thread_once() returns an implementation-specific non-zero error value.
