Re: help to unpack my record

[Henk Jonas]

christy,

typedef struct{
  char fields;
}DBPackedRecord;

/* fid should be an int but I don't know how to unpack
an int */
typedef struct{
  Char *fid;
  Char *fname;
}DBRecordType;

static void UnpackRecord(DBPackedRecord *packed,
DBRecordType *record){
 char *p;
 p = &packed->fields;
 record->fid=p;
 p +=StrLen(p) + 1;
 record->fname=p;
}

do bring this to work:
record->fid = p[0];
p++;

you extract one char, which is 1 byte, skip it and get the string just after it.

To extract an int you can write:
record->fid = (p[0] << 8) + p[1]; // big endian
p += 2;
