huffman_encode

Functions

int main(int argc, char *argv[])

huffman_encode cbfile [ infile ]

  • cbfile str

    • ascii codebook

  • infile str

    • int-type symbol sequence

  • stdout

    • bool-type codeword sequence

The below example encodes data.i and decodes it.

huffman_encode cbfile < data.i | huffman_decode cbfile > data.i2
# data.i and data.i2 should be identical

Parameters

  • argc – [in] Number of arguments.

  • argv – [in] Argument vector.

Returns

0 on success, 1 on failure.
