quickbms ( PutCT command )

[shekofte]

hello Dear Sir Luigi Auriemma

although this a banal subject but my scrupulosity don't let to skip it ...

i just managed to write a simple bms script that extract null terminated strings from a file and write them to a text file , so that they separated by a custom character like space, enter , comma ...
but in all case of using PutCT command for this subject , raised an exception !
please check what is wrong here :

the content of file :

Code: Select all

61 6C 70 68 61 00 62 65 74 61 00 67 61 6D 6D 61
00 64 65 6C 74 61 00 65 70 73 69 6C 6F 6E 00 7A
65 74 61 00 65 74 61 00 74 68 65 74 61 00 69 6F
74 61 00 6B 61 70 70 61 00 6C 61 6D 62 64 61 00
6D 75 00 6E 75 00 78 69 00 6F 6D 69 63 72 6F 6E
00 70 69 00 72 68 6F 00 73 69 67 6D 61 00 74 61
75 00 75 70 73 69 6C 6F 6E 00 70 68 69 00 63 68
69 00 70 73 69 00 6F 6D 65 67 61 00

the bms script i wrote :
although we can coding it in an alternative way just by adding another Put "0x20" BYTE after putct
but i don't know why the PutCT VAR TYPE CHAR [FILENUM] don't work properly even by -w switch according to the following documents of quickbms ?

Code: Select all

log MEMORY_FILE 0 0

for i = 0 < 20

get greek string
putct greek string -1 MEMORY_FILE
#putct greek string "0x20" MEMORY_FILE
Put "0x20" BYTE MEMORY_FILE

next i

log text.txt 0 64 MEMORY_FILE

PutCT VAR TYPE CHAR [FILENUM]
...
these are EXACTLY like the Get* functions except for the fact that
they perform write operations.
for using these commands on a phisical file (so MEMORY_FILEs
excluded) MUST be used the -w option at runtime needed for both
technical and security reasons.
if you want to write a string without the NULL delimiter use:
putct "your_string" string -1

GetCT VAR TYPE CHAR [FILENUM]
reads a string till the reaching of the CHAR delimiter.

arguments
VAR output variable
TYPE ignored because doesn't exist a type in this operation
CHAR the delimiter character as 8bit number
FILENUM number of the file associated to the archive (0)

examples:
GetCT NAME string 0x0a
GetCT NAME string 0x3b
set DELIMITER_BYTE long 0x0a
GetCT NAME string DELIMITER_BYTE

thanx for the feedback.

well, the crash obviously a problem in any case and so I will fix it.

but for the rest the putct command acted correctly.
in short putct with char 0x20 (the space) on a string like "test test" will store "test "

in your file you have the first string equal to "alpha" so there is no 0x20 char in that string, in this case putct can do nothing because it continue to store the string char by char till it finds a 0x20 char that doesn't exist.
so when it arrives at the end of the variable quickbms crashes because is out of the memory assigned to the "alpha" string.

so it's all ok, no problem (except the crash obviously eh eh eh)
