assignments for strings longer than 2 chars
- Use strlcpy concatenation instead of strlcat
- Make sure that what remains of iteration of the '_len' variable
for manual char assignment
is done in a safer way so mistakes are less possible
usage of strlcpy (when position/offset of previous strlcpy/snprintf call
is known. strlcat implementation in libretro-common makes implicit strlen
call, using strlcpy avoids this
* Reduce a bunch of local char variables by use of said clever usage,
should save up on local stack size usage
This reduces the amount of memory Retroarch needs to extract a ROM file.
It will only need the size of the ROM plus 128KiB to extract the file
from the ZIP. Previously it needed as much as twice that amount if the
compression ratio was not great. This is useful on memory constrained
platforms and has no impact on platforms with plenty of memory.
Handles all cases correctly (with and without MMAP, for cores that
require fullpath or not, small and big ZIP files).
Avoids the internal strlen call inside strdup, and strdup is a deprecated
function starting from MSVC2005 anyways.
NOTE: Do NOT pass STRLEN_CONST as n parameter to strldup, it needs to
be at least +1 character higher than the strlen return value of the same
string
as deprecated.
* Use fill_pathname_join_special in the vast majority of cases where
we can ensure out_path is a new empty string
* Get rid of some extension concatenation with strlcat where encountered
* Some general cleanups with NULL termination of strings that get immediately
passed to strlcpy/strlcpy-adjacent functions
(libretro-common) docs - document when string has to be non-NULL or else UB (undefined behavior)
(libretro-common) stdstring.c - string_hex_to_unsigned - make strlen call unneeded
* (joypad_connection) Small optimizations -
* Turn functions static where possible
* Hose strlen call out of loop
* (input_driver.c) General cleanups:
* Some small code/style nits
task_screenshot.c:
* Move widget callback function for screenshots to task_screenshot.c
(file_path.c):
* Turn get_pathname_num_slashes into static function
* path_linked_list_free - always returns true, so get rid of return value
* path_linked_list_new - fix function signature
* path_get_archive_delim - do not NULL-terminate string, already done by strlcpy later on
General:
* Slight optimizations - use int/size_t for loop counter variable instead of unsigned
* Take advantage of fact that strlcpy already NULL-terminates, so don't do this explicitly
outside if we're just going to end up calling strlcpy/fill_pathname_join on it anyway
