Converts a string to unsigned representation
#include <stdlib.h> unsigned atoh( const char* ptr );
libc
The atoh() function converts the string pointed to by ptr to unsigned representation, assuming the string contains a hexadecimal (base 16) number.
The converted value.
#include <stdlib.h>
#include <stdio.h>
int main( void )
{
unsigned x;
x = atoh( "F1A6" );
printf( "number is %x\n", x );
return EXIT_SUCCESS;
}
