How would you convert this hash function to quickbms.

Code:

#include 
#include 

__int64_t hashMagic(__int64_t a1, unsigned int a2)
{
  unsigned int i; 
  unsigned int v4; 

  v4 = 37;
  for ( i = 0; i < a2;   i ) 
    v4 = *(char *)(a1   i)   37 * v4;
    
  return v4;
}

int main()
{
    std::string str ("GAME/SKILL/25310/model/TEXTURE/001/Tex_c");
    __int64_t v1 = (__int64_t)"GAME/SKILL/25310/model/TEXTURE/001/Tex_c";
    int v2 = str.length();
    __int64_t v3 = hashMagic(v1, v2);
    printf("\nHash:""%X",(int) v3);
}

it should output

Hash:75963DE9

Code:

set VAR string "GAME/SKILL/25310/model/TEXTURE/001/Tex_c"
callfunction hashMagic 1
print "%v4|x%"

startfunction hashMagic
    strlen VARSZ VAR
    math v4 = 37
    for x = 0 < VARSZ
        getvarchr TMP VAR x
        xmath v4 "TMP   37 * v4"
    next x
endfunction

If you prefer to pass VAR as argument of hashMagic, just rename VAR as hashMagic_ARG1 in the function and call it as "callfunction hashMagic 1 VAR"
