Function caldera_bindings::avutil::av_realloc_f

pub unsafe extern "C" fn av_realloc_f(
    ptr: *mut c_void, 
    nelem: usize, 
    elsize: usize
) -> *mut c_void

Allocate, reallocate, or free a block of memory.

This function does the same thing as av_realloc(), except:

• It takes two size arguments and allocates nelem * elsize bytes, after checking the result of the multiplication for integer overflow.
• It frees the input block in case of failure, thus avoiding the memory leak with the classic @code{.c} buf = realloc(buf); if (!buf) return -1; @endcode pattern.
