Function deflateReset

#[export_name = "deflateReset"]
pub unsafe extern "C-unwind" fn deflateReset(
    strm: *mut z_stream,
) -> i32

This function is equivalent to deflateEnd followed by deflateInit_, but does not free and reallocate the internal compression state.

This function will leave the compression level and any other attributes that may have been set unchanged. The stream’s total_in, total_out, adler, and msg fields are initialized.

Returns

• Z_OK if success
• Z_STREAM_ERROR if the stream state was inconsistent

Safety

The caller must guarantee that

• Either
  • strm is NULL
  • strm satisfies the requirements of &mut *strm and was initialized with deflateInit_ or similar
