The upcoming shader cache needs this to be able to cache hash data from the gl_shader_program structure. Edited-by: Carl Worth <cworth@cworth.org>:> There is an internal implementation detail that the hash table underlying the struct string_to_uint_map stores each value internally as (value+1). The user needn't be very concerned with this (other than knowing that a value of UINT_MAX cannot be stored) since put() adds 1 and get() subtracts 1. So in this commit, rather than call the user's function directly with hash_table_call_foreach, we call through a wrapper that fixes up the off-by-one values before the caller's callback sees them. And with this wrapper in place, we also give a better signature to the callback function being passed to iterate(), so that this callback function can actually expect a char* and an unsigned argument, (rather than a couple of void* ).
