u_long strtoul (
const char *s,
char **endp
)
|
Arguments
|
s |
Pointer to a character string |
| endp |
Pointer to a storage area that will contain a pointer to the character
that stopped the conversion |
Return Value
The result of converting the character string pointed to by s to an unsigned
integer is
returned if the conversion was successful. 0 is returned if an error
occurred.
Explanation
The character string pointed to by s is converted to an unsigned
integer and its value is returned. Note that long and int are declared
as the same type in the R3000. The string pointed to by s must be
in one of the following formats: [ws][sn][ddd]
| [ws] |
White space (can be omitted) |
| [sn] |
Sign (can be omitted) |
| [ddd] |
Number string (can be omitted) |
strtoul() stops conversion when a character is encountered that
cannot be converted. A pointer to the character that terminated the conversion
is placed at the storage location specified by endp unless endp
is NULL.
