Function Documentation

nnFileType nnGuessFileType (  FILE *    f )

Determines the type of a file. Parameters: f  stdio file handle. Returns: File type.

nnNet* nnLoadNetwork (  void *    handle, int(*    nnRead)(void *handle, void *data, size_t len) )

Load a network. Parameters: handle  Opaque reading handle. nnRead  Pointer to input function. Returns: Loaded network or NULL upon failure.

nnNet* nnLoadNetworkFile (  FILE *    f )

Load a network from a file. Parameters: f  stdio file handle. Returns: Loaded network or NULL upon failure.

nnNet* nnLoadNetworkMem (  void *    data, size_t    len )

Load a network from memory. Parameters: data  Pointer to memory. len  Length of memory. Returns: Loaded network or NULL upon failure.

int nnSaveNetwork (  nnNet *    net, void *    handle, int(*    nnWrite)(void *handle, void *data, size_t len) )

Save a network's topology and weights. Parameters: net  Network to save. handle  Opaque writing handle. nnWrite  Pointer to output function. Returns: 1 if successful, 0 otherwise.

int nnSaveNetworkDynMem (  nnNet *    net, void **    ptr, size_t *    len )

Save a network's topology and weights to dynamically-allocated memory. Parameters: net  Network to save. Return values: ptr  Upon success, will contain pointer to saved network in memory. len  Upon success, will contain length of saved network. Returns: 1 if successful, 0 otherwise.

int nnSaveNetworkFile (  nnNet *    net, FILE *    f )

Save a network's topology and weights to a file. Parameters: net  Network to save. f  stdio file handle. Returns: 1 if successful, 0 otherwise.

int nnSaveNetworkMem (  nnNet *    net, void *    data, size_t    len )

Save a network's topology and weights to memory. Parameters: net  Network to save. data  Memory location to store network. len  Size of memory. Returns: 1 if successful, 0 otherwise.
