Crate fopencookie_sys 

Platform bindigns for fopencookie

Structs

_IO_FILE

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.

_IO_codecvt

_IO_cookie_io_functions_t

The structure with the cookie function pointers. The tag name of this struct is _IO_cookie_io_functions_t to preserve historic C++ mangled names for functions taking cookie_io_functions_t arguments. That name should not be used in new code.

_IO_marker

_IO_wide_data

Functions

fopencookie^⚠

Create a new stream that refers to the given magic cookie, and uses the given functions for input and output.

Type Aliases

FILE

The opaque type of streams. This is the definition used elsewhere.

_IO_lock_t

__off64_t

__off_t

__ssize_t

cookie_close_function_t

Close COOKIE.

cookie_io_functions_t

The structure with the cookie function pointers. The tag name of this struct is _IO_cookie_io_functions_t to preserve historic C++ mangled names for functions taking cookie_io_functions_t arguments. That name should not be used in new code.

cookie_read_function_t

Read NBYTES bytes from COOKIE into a buffer pointed to by BUF. Return number of bytes read.

cookie_seek_function_t

Move COOKIE’s file position to *POS bytes from the beginning of the file (if W is SEEK_SET), the current position (if W is SEEK_CUR), or the end of the file (if W is SEEK_END). Set *POS to the new file position. Returns zero if successful, nonzero if not.

cookie_write_function_t

Write NBYTES bytes pointed to by BUF to COOKIE. Write all NBYTES bytes unless there is an error. Return number of bytes written. If there is an error, return 0 and do not write anything. If the file has been opened for append (__mode.__append set), then set the file pointer to the end of the file and then do the write; if not, just write at the current file pointer.
