Thread-safe as all mapped function are thread-safe.

Parameters

globOptMember	One of the member names of crinitGlobOptStore_t (or one of the CRINIT_GLOBOPT_* constants).
val	Value to store. Type depends on the chosen member of crinitGlobOptStore_t. See function signatures of crinitGlobOptGet*().

Typedef Documentation

◆ crinitGlobOptStore_t

typedef struct crinitGlobOptStore_t crinitGlobOptStore_t

Structure definition for the global option storage.

Function Documentation

◆ attribute()

static crinitGlobOptStore_t crinitGenericGlobOptHelper __attribute__ ( (unused) )

static

Dummy instance for Generic Selection of members to work (see type-generic macros below).

◆ crinitGlobOptBorrow()

crinitGlobOptStore_t * crinitGlobOptBorrow ( void )

Provide direct thread-safe access to the central global option storage.

Calling thread will hold an exclusive lock on the central instance of crinitGlobOptStore_t. After the calling thread has finished its operations on the global option storage, it must release the lock using crinitGlobOptRemit().

Returns: A pointer to the central instance of crinitGlobOptStore_t on success, a NULL pointer if the lock could not be acquired.

◆ crinitGlobOptDestroy()

void crinitGlobOptDestroy ( void )

Deletes all set global options from storage.

Any allocated memory is freed. The function uses mutexes internally and is thread-safe.

◆ crinitGlobOptGetBoolean()

int crinitGlobOptGetBoolean	(	size_t	memberOffset,
		bool *	val
	)

Retrieves a boolean value from a global option.

Consider using the type-generic macro crinitGlobOptGet() which can be used with member names instead of offsets. Will lock the global option storage as long as needed and is thread-safe.

Parameters

memberOffset	The global option to set.
val	Return pointer for the retrieved boolean value.

Returns: 0 on success, -1 on error

◆ crinitGlobOptGetEnvSet()

int crinitGlobOptGetEnvSet	(	size_t	memberOffset,
		crinitEnvSet_t *	val
	)

Retrieves a crinitEnvSet_t value from a global option.

Consider using the type-generic macro crinitGlobOptGet() which can be used with member names instead of offsets. Will lock the global option storage as long as needed and is thread-safe.

Parameters

memberOffset	The global option to set.
val	Pointer to the crinitEnvSet_t instance to which the global one will be duplicated.

Returns: 0 on success, -1 on error

◆ crinitGlobOptGetInteger()

int crinitGlobOptGetInteger	(	size_t	memberOffset,
		int *	val
	)

Retrieves an integer value from a global option.

Consider using the type-generic macro crinitGlobOptGet() which can be used with member names instead of offsets. Will lock the global option storage as long as needed and is thread-safe.

Parameters

memberOffset	The global option to set.
val	Return pointer for the retrieved integer value.

Returns: 0 on success, -1 on error

◆ crinitGlobOptGetString()

int crinitGlobOptGetString	(	size_t	memberOffset,
		char **	val
	)

Retrieves a string value from a global option.

Consider using the type-generic macro crinitGlobOptGet() which can be used with member names instead of offsets. Will lock the global option storage as long as needed and is thread-safe.

Will allocate memory for the returned string. When no longer in use, free() should be called on the returned pointer to free the memory.

Parameters

memberOffset	The offset of the member of the global option struct to set.
val	Return pointer for the retrieved string. Memory will be allocated.

Returns: 0 on success, -1 on error

◆ crinitGlobOptGetUnsignedLL()

int crinitGlobOptGetUnsignedLL	(	size_t	memberOffset,
		unsigned long long *	val
	)

Retrieves an unsigned long long value from a global option.

val	Return pointer for the unsigned long long integer value.

Returns: 0 on success, -1 on error

◆ crinitGlobOptInitDefault()

int crinitGlobOptSetUnsignedLL	(	size_t	memberOffset,
		unsigned long long	val
	)

Stores an unsigned long long value for a global option.
