Function svn_io_file_readline 

pub unsafe extern "C" fn svn_io_file_readline(
    file: *mut apr_file_t,
    stringbuf: *mut *mut svn_stringbuf_t,
    eol: *mut *const c_char,
    eof: *mut svn_boolean_t,
    max_len: apr_size_t,
    result_pool: *mut apr_pool_t,
    scratch_pool: *mut apr_pool_t,
) -> *mut svn_error_t

Read a line of text from a file, up to a specified length.

Allocate @a *stringbuf in @a result_pool, and read into it one line from @a file. Reading stops either after a line-terminator was found or after @a max_len bytes have been read.

If end-of-file is reached or @a max_len bytes have been read, and @a eof is not NULL, then set @a *eof to @c TRUE.

The line-terminator is not stored in @a *stringbuf. The line-terminator is detected automatically and stored in @a *eol if @a eol is not NULL. If EOF is reached and @a file does not end with a newline character, and @a eol is not NULL, @ *eol is set to NULL.

@a scratch_pool is used for temporary allocations.

Hint: To read all data until a line-terminator is hit, pass APR_SIZE_MAX for @a max_len.
