esp_pm_lock struct

Take a power management lock Once the lock is taken, power management algorithm will not switch to the mode specified in a call to esp_pm_lock_create, or any of the lower power modes (higher numeric values of 'mode'). The lock is recursive, in the sense that if esp_pm_lock_acquire is called a number of times, esp_pm_lock_release has to be called the same number of times in order to release the lock. This function may be called from an ISR. This function is not thread-safe w.r.t. calls to other esp_pm_lock_* functions for the same handle.

Release the lock taken using esp_pm_lock_acquire. Call to this functions removes power management restrictions placed when taking the lock. Locks are recursive, so if esp_pm_lock_acquire is called a number of times, esp_pm_lock_release has to be called the same number of times in order to actually release the lock. This function may be called from an ISR. This function is not thread-safe w.r.t. calls to other esp_pm_lock_* functions for the same handle.

Delete a lock created using esp_pm_lock The lock must be released before calling this function. This function must not be called from an ISR.

Initialize a lock handle for certain power management parameter When lock is created, initially it is not taken. Call esp_pm_lock_acquire to take the lock. This function must not be called from an ISR.
