Functions

• blosc_cbuffer_complib^⚠
  Return the compressor library/format used in a compressed buffer.
• blosc_cbuffer_metainfo^⚠
  Return meta-information about a compressed buffer, namely the type size (typesize), as well as some internal flags.
• blosc_cbuffer_sizes^⚠
  Return information about a compressed buffer, namely the number of uncompressed bytes (nbytes) and compressed (cbytes). It also returns the blocksize (which is used internally for doing the compression by blocks).
• blosc_cbuffer_validate^⚠
  Checks that the compressed buffer starting at cbuffer of length cbytes may contain valid blosc compressed data, and that it is safe to call blosc_decompress/blosc_decompress_ctx/blosc_getitem.
• blosc_cbuffer_versions^⚠
  Return information about a compressed buffer, namely the internal Blosc format version (version) and the format for the internal compressor used (compversion).
• blosc_compcode_to_compname^⚠
  Get the compname associated with the compcode.
• blosc_compname_to_compcode^⚠
  Return the compressor code associated with the compressor name.
• blosc_compress^⚠
  Compress a block of data in the src buffer and returns the size of the compressed block. The size of src buffer is specified by nbytes. There is not a minimum for src buffer size (nbytes).
• blosc_compress_ctx^⚠
  Context interface to blosc compression. This does not require a call to blosc_init() and can be called from multithreaded applications without the global lock being used, so allowing Blosc be executed simultaneously in those scenarios.
• blosc_decompress^⚠
  Decompress a block of compressed data in src, put the result in dest and returns the size of the decompressed block.
• blosc_decompress_ctx^⚠
  Context interface to blosc decompression. This does not require a call to blosc_init() and can be called from multithreaded applications without the global lock being used, so allowing Blosc be executed simultaneously in those scenarios.
• blosc_destroy^⚠
  Destroy the Blosc library environment.
• blosc_free_resources^⚠
  Free possible memory temporaries and thread resources. Use this when you are not going to use Blosc for a long while. In case of problems releasing the resources, it returns a negative number, else it returns 0.
• blosc_get_blocksize^⚠
  Get the internal blocksize to be used during compression. 0 means that an automatic blocksize is computed internally (the default).
• blosc_get_complib_info^⚠
  Get info from compression libraries included in the current build. In compname you pass the compressor name that you want info from.
• blosc_get_compressor^⚠
  Returns the current compressor that is being used for compression.
• blosc_get_nthreads^⚠
  Returns the current number of threads that are used for compression/decompression.
• blosc_get_version_string^⚠
  Return the version of the C-Blosc library in string format.
• blosc_getitem^⚠
  Get nitems (of typesize size) in src buffer starting in start. The items are returned in dest buffer, which has to have enough space for storing all items.
• blosc_init^⚠
  Initialize the Blosc library environment.
• blosc_list_compressors^⚠
  Get a list of compressors supported in the current build. The returned value is a string with a concatenation of “blosclz”, “lz4”, “lz4hc”, “snappy”, “zlib” or “zstd “separated by commas, depending on which ones are present in the build.
• blosc_set_blocksize^⚠
  Force the use of a specific blocksize. If 0, an automatic blocksize will be used (the default).
• blosc_set_compressor^⚠
  Select the compressor to be used. The supported ones are “blosclz”, “lz4”, “lz4hc”, “snappy”, “zlib” and “zstd”. If this function is not called, then “blosclz” will be used by default.
• blosc_set_nthreads^⚠
  Initialize a pool of threads for compression/decompression. If nthreads is 1, then the serial version is chosen and a possible previous existing pool is ended. If this is not called, nthreads is set to 1 internally.
• blosc_set_splitmode^⚠
  Set the split mode.
