sprintf

[selimsl]

char asciihex[5];
short int datax=10;
sprintf(asciihex,"%4X",datax);

As you know, result of this code is : " A"

Is there any function to reverse this operation.I mean,

asciihex[5]="   A";
datax=function(asciihex);

result is :datax=10

Thanks in advice...

char asciihex[5]="   A";
short int datax;
sscanf(asciihex,"%hX",&datax);

Or use strtol() from stdlib.h:

datax = strtol(asciihex,0,16);
