Convert char* eg. "0x1A" to char* 0x1A (hexadecimal) 1

Hi, I have the following:

char myvar[4] = "0x3B"
unsigned char mac[6];
mac[0] = 0x1A;
mac[1] = 0x22;
....

the question is how can I do this new assignment:

mac[2] = content of myvar[4];

but it has to be stored it in the same format that mac[1] = 0x1A (hexadecimal)

thx.

Try strtol if you have it.

Would strtol() work with a hex number, or if it starts with "0x"?
I know sscanf() would work.

thx a lot xwb and cpjust. Finally cpjust's solution did the trick.
