mmosal_semb_give()

bool mmosal_semb_give

(

struct mmosal_semb *

semb

)

Give a binary semaphore.

Warning

May not be invoked from an ISR.

Parameters

semb	The semaphore to give.

Returns

true on success, else false.

mmosal_semb_give_from_isr()

bool mmosal_semb_give_from_isr

(

struct mmosal_semb *

semb

)

Warning

May only be invoked from an ISR.

Parameters

semb	The semaphore to give.

Returns

true on success, else false.

Definition at line 93 of file mmosal_shim_bootloader.c.

mmosal_semb_wait()

bool mmosal_semb_wait	(	struct mmosal_semb *	semb,
		uint32_t	timeout_ms
	)

Wait for a counting semaphore.

Parameters

semb	The semaphore to wait for.
timeout_ms	Timeout after which to give up waiting (in milliseconds).

Returns

true if the the semaphore was taken successfully, else false.
