strtoul
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Converts a partial string to an unsigned long integer.
<stdlib.h>
unsigned long strtoul(const char *s, char **endptr,
s
endptr
base
Returns the converted number if successful; otherwise, returns 0.
If base is zero, strtol attempts to determine the base automatically.
It can be octal, determined by a leading zero, hexadecimal, determined
by a leading 0x or 0X, or decimal in any other case. If base is specified
strtol converts a sequence of digits and letters a-z (case insensi-
tive), where a-z represents the numbers 10-36. Conversion stops when
an out of base number is encountered. endptr will point to the remain-
der of the string starting with the first unconverted character. If a range
error occurs, errno will be set.
#include <stdio.h>
#include <stdlib.h> /* for strtoul */
int main(void)
{
}
Output:
String = "12BGET3"
Stopped at: T3
String = "0x1234Number"
Stopped at: Number
String = "-123abc"
Stopped at: abc
int base);
char *end;
char a[] = "12BGET3";
char b[] = "0x1234Number";
char c[] = "-123abc";
unsigned long x;
x = strtoul(a, &end, 25);
printf("String = \"%s\"
printf("Stopped at: %s\n\n", end );
x = strtoul(b, &end, 0);
printf("String = \"%s\"
printf("Stopped at: %s\n\n", end );
x = strtoul(c, &end, 0);
printf("String = \"%s\"
printf("Stopped at: %s\n\n", end );
