Function Documentation

secp256k1_scratch_alloc()

static void* secp256k1_scratch_alloc ( secp256k1_scratch *  scratch, size_t  n  )

static

Returns a pointer into the most recently allocated frame, or NULL if there is insufficient available space

secp256k1_scratch_allocate_frame()

static int secp256k1_scratch_allocate_frame ( secp256k1_scratch *  scratch, size_t  n, size_t  objects  )

static

Attempts to allocate a new stack frame with n available bytes. Returns 1 on success, 0 on failure

secp256k1_scratch_create()

static secp256k1_scratch* secp256k1_scratch_create ( const secp256k1_callback *  error_callback, size_t  max_size  )

static

secp256k1_scratch_deallocate_frame()

static void secp256k1_scratch_deallocate_frame ( secp256k1_scratch *  scratch )

static

Deallocates a stack frame

secp256k1_scratch_destroy()

static void secp256k1_scratch_destroy ( secp256k1_scratch *  scratch )

static

secp256k1_scratch_max_allocation()

static size_t secp256k1_scratch_max_allocation ( const secp256k1_scratch *  scratch, size_t  n_objects  )

static

Returns the maximum allocation the scratch space will allow
