CHARTYPE *filename; CHARTYPE *macro_ext; short *errnum; DESCRIPTION The get_valid_macro_file_name function determines the fully qualified file name for the supplied macroname. This routine is also used to find THE Language Definition files. If the macroname contains any path specifiers, then the macro name is used as the filename and a check is made to ensure that the file exists and is readable. If the macroname does not contain any path specifiers, each directory in the MACROPATH variable is searched for a file that consists of the macroname appended with the current value for macro_ext. If a file is found, it is checked to ensure it is readable. RETURN VALUE If a file is found based on the above matching process, the fully qualified file name is copied into filename, errnum is set to 0 and the function returns with RC_OK. If a file is not found, the macroname is copied into filename, the error number of the error message is copied into errnum and the function returns with RC_FILE_NOT_FOUND. If a file is found but the file is not readable, the macroname is copied into filename, the error number of the error message is copied into errnum and the function returns with RC_ACCESS_DENIED. *******************************************************************************/ #ifdef HAVE_PROTO short get_valid_macro_file_name(CHARTYPE *inmacroname,CHARTYPE *filename,CHARTYPE *macro_ext,short *errnum) #else short get_valid_macro_file_name(inmacroname,filename,macro_ext,errnum) CHARTYPE *inmacroname,*filename,*macro_ext;
