convert a string to unsigned representation
unsigned atoh( const char *ptr );
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); }
