strlen - get string length
Návod, kniha: POSIX Programmer's Manual
#include <string.h>
size_t strlen(const char *
s);
The
strlen() function shall compute the number of bytes in the string to
which
s points, not including the terminating null byte.
The
strlen() function shall return the length of
s; no return
value shall be reserved to indicate an error.
No errors are defined.
The following sections are informative.
The following example sets the maximum length of
key and
data by
using
strlen() to get the lengths of those strings.
#include <string.h>
...
struct element {
char *key;
char *data;
};
...
char *key, *data;
int len;
*keylength = *datalength = 0;
...
if ((len = strlen(key)) > *keylength)
*keylength = len;
if ((len = strlen(data)) > *datalength)
*datalength = len;
...
None.
None.
