39 ; --- res_exists ---
40 ;
41 ; On entry: R0 == pointer to pathname
42 ;
43 ; On exit: CS if the file exists, CC otherwise
44 ;
45 ; Use: Tries to find the named file. The file is deemed to exist
46 ; if OS_File can return a valid object type for it (i.e. not
47 ; `non-existant object' or actually raising errors).

51 ; --- res_country ---
52 ;
53 ; On entry: R0 == pointer to a buffer to use
54 ;
55 ; On exit: R0 == pointer to country name (may not be in the buffer)
56 ;
57 ; Use: Reads the name of the current country. If no name can be
58 ; found, it returns a pointer to the string `UK' which should
59 ; do as a suitable default
60
61 IMPORT res_country
62
63 ; --- res_find ---
64 ;
65 ; On entry: R0 == pointer to resource filename
66 ; R1 == pointer to buffer to build filename in
67 ;
68 ; On exit: R0 == pointer to start of full pathname (R1 on entry)
69 ; R1 == pointer to terminating null character
70 ; CS if the file could actually be found, CC otherwise
71 ;
72 ; Use: Locates a resource file. It searches, in order:
73 ;
74 ; * resPrefix.Resources.leaf[suffix]
75 ; * resPrefix.Resources.country.leaf[suffix]
76 ; * resPrefix.leaf[suffix]
77 ;
78 ; returning the last if none of them could be found. Note
79 ; that `country' here is the currently configured country
80 ; setting, and `suffix' is the WIMP mode aspect ratio suffix
81 ; for the current mode (RISC OS 3 only).
