Expand description

The tag name of this struct is _IO_FILE to preserve historic C++ mangled names for functions taking FILE* arguments. That name should not be used in new code.

Fields§

§_flags: c_int

High-order word is _IO_MAGIC; rest is flags.

§_IO_read_ptr: *mut c_char

Current read pointer

§_IO_read_end: *mut c_char

End of get area.

§_IO_read_base: *mut c_char

Start of putback+get area.

§_IO_write_base: *mut c_char

Start of put area.

§_IO_write_ptr: *mut c_char

Current put pointer.

§_IO_write_end: *mut c_char

End of put area.

§_IO_buf_base: *mut c_char

Start of reserve area.

§_IO_buf_end: *mut c_char

End of reserve area.

§_IO_save_base: *mut c_char

Pointer to start of non-current get area.

§_IO_backup_base: *mut c_char

Pointer to first valid character of backup area

§_IO_save_end: *mut c_char

Pointer to end of non-current get area.

§_markers: *mut _IO_marker§_chain: *mut _IO_FILE§_fileno: c_int§_flags2: c_int§_old_offset: __off_t

This used to be _offset but it’s too small.

§_cur_column: c_ushort

1+column number of pbase(); 0 is unknown.

§_vtable_offset: c_schar§_shortbuf: [c_char; 1]§_lock: *mut _IO_lock_t§_offset: __off64_t§_codecvt: *mut _IO_codecvt

Wide character stream stuff.

§_wide_data: *mut _IO_wide_data§_freeres_list: *mut _IO_FILE§_freeres_buf: *mut c_void§__pad5: usize§_mode: c_int§_unused2: [c_char; 20]

Make sure we don’t get into trouble again.
