Locates the first executable named program in the user's path, in the same way that
execvp() would locate it. Returns a string with the absolute path name, or

PATHEXT environment variable (if that doesn't exist, the suffixes .com, .exe, and .bat) in turn, and then look for the resulting file name in the same way as CreateProcess() would. This means first in the directory where the program was loaded from, then in the current directory, then in the Windows 32-bit system directory, then in the Windows directory, and finally in the directories in the
PATH environment variable. If the program is found, the return value contains the full name including the type suffix.
