23// get_LANG_string is the main parser called for each language dependent
24// string in a language header file. (eg: "Francais.h" or "Francais.lng")
25// Call values for all input arguments should be addresses of string pointers
26// LANG_p_p is for file to be scanned, moved to point beyond scanned data.
27// id_p_p is for a string defining the index value (suitable for 'atoi')
28// value_p_p is for the string value itself (not NUL-terminated)
29// The function returns the length of each string found, but -1 at EOF,
30// and various error codes less than -1 (-2 etc) for various syntax errors,
31// which also applies to EOF occurring where valid macro parts are expected.
