}

Structure for custom file access.

Fields

m_FileLen: c_ulong

File length, in bytes.

m_GetBlock: Option<unsafe extern "C" fn(param: *mut c_void, position: c_ulong, pBuf: *mut c_uchar, size: c_ulong) -> c_int>

A function pointer for getting a block of data from a specific position. Position is specified by byte offset from the beginning of the file. The pointer to the buffer is never NULL and the size is never 0. The position and size will never go out of range of the file length. It may be possible for FPDFSDK to call this function multiple times for the same position. Return value: should be non-zero if successful, zero for error.

m_Param: *mut c_void

A custom pointer for all implementation specific data. This pointer will be used as the first parameter to the m_GetBlock callback.
