DESCRIPTION
or converts the character string pointed to by str to or representation, respectively. or converts the character string pointed to by str to or representation, respectively. The string is scanned up to the first character inconsistent with the base. Leading "white-space" characters (as defined by in ctype(3C)) are ignored. If no conversion can take place, zero is returned. If base is greater than or equal to 2 and less than or equal to 36, it is used as the base for conversion. After an optional leading sign, leading zeros are ignored, and or is ignored if base is 16. If base is zero, the string itself determines the base as follows: after an optional leading sign, a leading zero indicates octal conver- sion; a leading or indicates hexadecimal conversion. Otherwise, decimal conversion is used. If the value of ptr is not a pointer to the character terminating the scan is returned in the location pointed to by ptr. If no integer can be formed, the location pointed to by ptr is set to str, and zero is returned. is equivalent to is equivalent to is equivalent to RETURN VALUE
