Process Control Function
int _spawnvpe(int mode, const char *cmdname, const char *const *argv, const char *const *envp);
int _wspawnvpe(int mode, const wchar_t *cmdname, const wchar_t *const *argv, const wchar_t *const *envp);
int _tspawnvpe(int mode, const TCHAR *cmdname, const TCHAR *const *argv, const TCHAR *const *envp);
Internationalization (I18n) Function Overview
The _spawnvpe function creates and executes a new process for the file cmdname, using the PATH environment variable to find the file, and called with an array of pointers to command-line arguments in argv and an array of pointers to environment strings in envp. The function returns -1 in the event of an error, or a value that depends on the setting of mode.
_wspawnvpe is the wide-character version of _spawnvpe that supports wide-character string arguments.
_tspawnvpe is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _spawnvpe or _wspawnvpe.
See the MSDN library for more information.
I18n Issues
Use the appropriate version of the function as required for internationalization support, noting the following:
For a Windows MBCS application, _spawnvpe depends on the multibyte code page in effect. By default, the multibyte code page is set to the system-default ANSI code page obtained from the operating system at program startup.
Use _getmbcp and _setmbcp to query or change the current multibyte code page, respectively.
Recommended Replacements*
*If you're already using the recommended function, see I18n Issues for other reasons why Globalyzer is detecting the function.
