NAME¶
globus_thread_once - One-time execution
- One-time execution.
SYNOPSIS¶
Data Structures¶
union globus_thread_once_t
Thread once structure.
Macros¶
#define GLOBUS_THREAD_ONCE_INIT { .none = 0 }
Thread once initializer value.
Functions¶
int globus_thread_once (globus_thread_once_t *once,
void(*init_routine)(void))
Execute a function one time.
Detailed Description¶
One-time execution.
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().
Function Documentation¶
int globus_thread_once (globus_thread_once_t * once, void(*)(void) init_routine)¶
Execute a function one time. The globus_thread_once() function will execute the function pointed to by its 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 once value must be a static value initialized to GLOBUS_THREAD_ONCE_INIT.
Parameters
init_routine Function to execute one time. It is called with no parameters.
