Function mupdf_sys::fz_resize_buffer

pub unsafe extern "C" fn fz_resize_buffer(
    ctx: *mut fz_context, 
    buf: *mut fz_buffer, 
    capacity: usize
)

Ensure that a buffer has a given capacity, truncating data if required.

capacity: The desired capacity for the buffer. If the current size of the buffer contents is smaller than capacity, it is truncated.
