60 * Convert a single hex character to its binary value.
61 * Returns -1 if given character is not a value hex character.
63 extern int __hex(char ch);
66 * Convert the hex data in 'buf' into 'count' bytes to be placed in 'mem'.
67 * Returns a pointer to the character in mem AFTER the last byte written.
69 extern char *__unpack_bytes_to_mem(char *buf, char *mem, int count);
72 * While finding valid hex chars, build an unsigned long int.
73 * Return number of hex chars processed.
75 extern int __unpack_ulong(char **ptr, unsigned long *val);
78 * Unpack 'count' hex characters, forming them into a binary value.
79 * Return that value as an int. Adjust the source pointer accordingly.
