Detailed Description

Functions for parsing the unicode map file.

Author:

Daniel Roelker <droelker@atlas.cs.cuc.edu>

This file contains the routines for parsing generated IIS unicode maps. We read in the map, find where the codepage is located in the map, and convert the codepoint maps, and store in the supplied array.

Function Documentation

static int FindCodePage (  FILE *  fFile, int  iCodePage )  [static]

Locate the codepage mapping the IIS Unicode Map file. We iterate through the file lines until we get to the codepage reference. We then return that it was found successfully, and the FILE pointer is located on the codepoint mapping line. Parameters: fFile  the codemap file pointer iCodePage  the codepage number Returns: int Return values: HI_FATAL_ERR  Did not find the codepage listing. HI_SUCCESS  function successful Definition at line 54 of file hi_ui_iis_unicode_map.c. References buffer, CODEPAGE_SEPARATORS, HI_FATAL_ERR, HI_SUCCESS, MAX_BUFFER, strtok_r, and strtol(). Referenced by hi_ui_parse_iis_unicode_map().

int hi_ui_parse_iis_unicode_map (  int **  iis_unicode_map, char *  filename, int  iCodePage )

Parses an IIS Unicode Map file and store in the supplied array. This routine allocates the necessary memory to store the array values in, and parses the supplied filename. Parameters: iis_unicode_map  double pointer so we can allocate the memory filename  the name of the file to open and parse iCodePage  the codpage number to read the mappings from Returns: integer Return values: HI_INVALID  ARG invalid argument HI_MEM_ALLOC_FAIL  memory allocation failed HI_INVALID_FILE  Could not open the supplied filename HI_SUCCESS  function was successful Definition at line 201 of file hi_ui_iis_unicode_map.c. References FindCodePage(), HI_INVALID_ARG, HI_INVALID_FILE, HI_MEM_ALLOC_FAIL, HI_SUCCESS, HI_UI_NON_ASCII_CODEPOINT, MapCodePoints(), memset, NULL, and xmalloc(). Referenced by ProcessIISUnicodeMap().

static int MapCodePoints (  FILE *  fFile, int *  iis_unicode_map )  [static]

Read the codepoint mapping and covert to codepoint and ASCII. This is where the bulk of the work is done. We read in 9 bytes at a time because the mappings are in chunks of 8 (+1 for the NULL at the end). The chunks are as follows: xxxx:xx (the first set of 4 is the codepoint, the second set is the ASCII representation) We then convert and check these values before storing them in the supplied array. Parameters: fFile  the unicode map file pointer iis_unicode_map  the array to store the mappings in Returns: integer Return values: HI_FATAL_ERR  there was an error while parsing the file HI_SUCCESS  function was successful Definition at line 116 of file hi_ui_iis_unicode_map.c.
