Struct mozjpeg_sys::jpeg_common_struct
[−]
[src]
#[repr(C)]pub struct jpeg_common_struct { pub err: *mut jpeg_error_mgr, pub mem: *mut jpeg_memory_mgr, pub progress: *mut jpeg_progress_mgr, pub client_data: *mut c_void, pub is_decompressor: boolean, pub global_state: c_int, }
Routines that are to be used by both halves of the library are declared to receive a pointer to this structure. There are no actual instances of jpeg_common_struct, only of jpeg_compress_struct and jpeg_decompress_struct.
Fields
err: *mut jpeg_error_mgr
mem: *mut jpeg_memory_mgr
progress: *mut jpeg_progress_mgr
Progress monitor, or NULL if none
client_data: *mut c_void
Available for use by application
is_decompressor: boolean
So common code can tell which is which
global_state: c_int
For checking call sequence validity
