Function Documentation

void hardware_init

(

void

)

Initialize some hardware-specific variables, which are needed by other hardware_* functions.

References hardware_cores().

void hardware_memlimit_set

(

uint64_t

memlimit

)

Set custom memory usage limit. This is used for both encoding and decoding. Zero indicates resetting the limit back to defaults.

References memlimit_custom.

uint64_t hardware_memlimit_encoder

(

void

)

Get the memory usage limit for encoding. By default this is 90 % of RAM.

uint64_t hardware_memlimit_decoder

(

void

)

Get the memory usage limit for decoding. By default this is 30 % of RAM.
