NAME

bson_realloc_ctx() - This function is identical to bson_realloc() except it takes a context parameter. This is useful when working with pooled or specific memory allocators.

SYNOPSIS

void *
bson_realloc_ctx (void  *mem,
                  size_t num_bytes,
                  void  *ctx);

PARAMETERS

mem
A memory region.

num_bytes
A size_t containing the requested size.

ctx
A consumer-specific pointer or NULL \&.

DESCRIPTION

This function is identical to bson_realloc(3) except it takes a context parameter. This is useful when working with pooled or specific memory allocators.

Pages related to bson_realloc_ctx

  • bson_realloc_func (3) - This is a prototype for pluggable realloc functions used through the Libbson library. If you wish to use a custom allocator this is one way to do it. Additionally, bson_realloc_ctx() is a default implementation of this prototype.
  • bson_realloc (3) - This is a portable realloc() wrapper.
  • bson_reader_destroy (3) - Destroys and releases all resources associated with reader.
  • bson_reader_destroy_func_t (3) - An optional callback function that will be called when a bson_reader_t created with bson_reader_new_from_handle is destroyed with bson_reader_destroy().
  • bson_reader_new_from_data (3) - The bson_reader_new_from_data() function shall create a new bson_reader_t using the buffer supplied. data is not copied and MUST be valid for the lifetime of the resulting bson_reader_t.
  • bson_reader_new_from_fd (3) - The bson_reader_new_from_fd() function shall create a new bson_reader_t that will read from the provided file-descriptor.
  • bson_reader_new_from_file (3) - Creates a new bson_reader_t using the file denoted by filename.
  • bson_reader_new_from_handle (3) - This function allows for a pluggable data stream for the reader. This can be used to read from sockets, files, memory, or other arbitrary sources.
  • bson_reader_read (3) - The bson_reader_read() function shall read the next document from the underlying file-descriptor or buffer.
  • bson_reader_read_func_t (3) - A callback function that will be called by bson_reader_t to read the next chunk of data from the underlying opaque file descriptor.
  • bson_reader_set_destroy_func (3) - Allows for setting a callback to be executed when a reader is destroyed. This should only be used by implementations implementing their own read callbacks.
  • bson_reader_set_read_func (3) - Sets the function to read more data from the underlying stream in a custom bson_reader_t.
