ios - Bad Access/Pointer Issue in Objective-C -

i've got next bit of code:

byte * tokenout = null; (int = 0; < sizeof(tknout); i++) { tokenout[i * 2] = (tknout[i] >> 8); tokenout[(i * 2) + 1] = (tknout[i] & 0xff); }

but generates exc_bad_access error upon running when seek update tokenout. i'd appreciate if tell me i'm doing wrong!

thanks!

you dereferencing null pointer.

try

byte whatever; byte *outtoken = &whatever; // rest.

now there valid memory write to.

except still have issues because write past end of variable. maybe wanted array?

sizeof(outtkn) homecoming 1 (1 byte)
