### Function Macro

# GLibtry_renew

since: 2.8

#### Declaration [src]

    #define g_try_renew (
      struct_type,
      mem,
      n_structs
    )

#### Description [src]

Attempts to reallocate the memory pointed to by `mem`, so that it now has space for `n_structs` elements of type `struct_type`, and returns `NULL` on failure. Contrast with g_renew(), which aborts the program on failure. It returns the new address of the memory, which may have been moved. The function returns `NULL` if an overflow occurs.
