Исходник [JS] Get Samp Version

[Fr0z3n]

This is function for getting samp versions(From 0.3.7 R1 - 0.3.7 R4 - 2). You can use it on new cleo extension Cleo Redux

The code contains 2 functions:
- get_samp_version_id
- get_samp_version_name

You can see more about this function here.

/*
    get_samp_version_id function is reading the "IMAGE_FILE_HEADER" of samp.dll (TimeDateStamp to be specific)
    That TimeDateStamp is based on compilation time. See this for more info:
    https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#file-headers
 
    "TimeDateStamp = The low 32 bits of the number of seconds since 00:00 January 1, 1970 (a C run-time time_t value), that indicates when the file was created. "
 
    In most versions that time stamp is located at offset 0x128 from samp.dll. In "0.3.7 R3 1" it is located at 0x120 offset though.
