when trying to use -p <frame> -r <count> -t <interval> , npg ignores time interval , and gives a burst sized <count>

great tool beside , Thanks for your work

1.In File npgparser.c,

 Function: char *ParsePacketID(char *line, int *Advanced),
 LINE 154: PktID = MAlloc(sizeof(char *)*AppendSize);
 should be changed into: PktID = MAlloc(sizeof(char)*AppendSize); 
 LINE 166: WorkingPacketID = MAlloc(sizeof(char*)*(PktIDSize+AppendSize));
 should be changed into: WorkingPacketID = MAlloc(sizeof(char)*(PktIDSize+AppendSize));
 LINE 179: PktID = MAlloc(sizeof(char*)*strlen(WorkingPacketID));
 should be changed into: PktID = MAlloc(sizeof(char*)*strlen(WorkingPacketID));

2.In File npgfile.c,

 char     HexByte[1];
 should be changed into: char     HexByte[2];  

3.In File npgutils.c,

 Function: u_int32_t Chars2Hex(char *chex, char cHexLength) 
 LINE 102: if ( chex[i] > 0x29  && chex[i] < 0x40 ) Digit[i] = chex[i] & 0x0f; //if 0 to 9
 should be changed into if ( chex[i] > 0x2F  && chex[i] < 0x3A ) Digit[i] = chex[i] & 0x0f; //if 0 to 9
