inflateBackInit_

Function inflateBackInit_

pub unsafe extern "C-unwind" fn inflateBackInit_(
    strm: z_streamp,
    windowBits: c_int,
    window: *mut c_uchar,
    version: *const c_char,
    stream_size: c_int,
) -> c_int

Expand description

Initializes the state for decompression

§Returns

Z_OK if success
Z_MEM_ERROR if there was not enough memory
Z_VERSION_ERROR if the zlib library version is incompatible with the version assumed by the caller
Z_STREAM_ERROR if a parameter is invalid, such as a null pointer to the structure

§Safety

The caller must guarantee that

Either
- strm is NULL
- strm satisfies the requirements of &mut *strm
Either
- version is NULL
- version satisfies the requirements of core::ffi::CStr::from_ptr
If strm is not NULL, the following fields contain valid values
- zalloc
- zfree
- opaque
