What is Linux equivalent of LPTSTR & LPCSTR?
c, linux, lpcstr, lptstr, porting
Solution
In Linux you don't usually use `wchar_t` for library API functions. Most libraries use UTF-8 encoded strings, so they take as strings plain arrays of NUL-terminated chars (IMO that is far better than duplicating all the functions with ANSI and Unicode versions).
So, with that in mind:
- `LPCTSTR`, `LPCSTR`, `LPCWSTR` -> `const char *`.
- `LPTSTR`, `LPSTR`, `LPWSTR` -> `char *`.
If you insist in using Unicode functions, MS style, you have to be aware that they actually use UTF-16 encoded strings, and `wchar_t` is not a portable type, as its size is not specified by the language. Instead you can use `uint16_t`:
- `LPCWSTR` -> `const uint16_t *`.
- `LPWSTR` -> `uint16_t *`.
And if you want to be extra MS compatible, you can use the `UNICODE` macro to conditionally typedef the `LPTSTR` and `LPTCSTR` into one of the others, but that's probably unneeded for your problem.
Problem
I am converting windows library to linux. I need to find LPTSTR and LPCSTR in linux. I get to know that i can use wchar_t can be used but I am not really sure about using it. one of the method that uses LPTSTR is as follows: ``` void ErrorExit(LPTSTR zFunction) { } ``` Any help will be appreciated!
