| char * qstrreplace |
( |
const char * | mode, |
|
|
char * | srcstr, |
|
|
const char * | tokstr, |
|
|
const char * | word ) |
Replace tokens or strings in a source string using the given mode.
- Parameters
-
| mode | replace mode |
| srcstr | source string |
| tokstr | token or string to match |
| word | replacement string |
- Returns
- pointer to the result string on success, or NULL on failure.
- Note
- The mode has two characters.
The first character selects how matching works:
- t matches each character in tokstr as a token.
- s matches tokstr as a full string.
The second character selects where the result is stored:
- n returns a newly allocated string.
- r writes the result back into srcstr.
When r is used, srcstr must have enough space for the result, and it must point to writable memory.
Supported modes:
- tn : token replace, return a new string
- tr : token replace, update srcstr
- sn : string replace, return a new string
- sr : string replace, update srcstr
char srcstr[256], *retstr;
char mode[4][2+1] = {"tn", "tr", "sn", "sr"};
for (i = 0; i < 4; i++) {
strcpy(srcstr, "Welcome to The qDecoder Project.");
printf("before %s : srcstr = %s\n", mode[i], srcstr);
printf("after %s : srcstr = %s\n", mode[i], srcstr);
printf(" retstr = %s\n\n", retstr);
if (mode[i][1] == 'n') free(retstr);
