NAME

       strlen - get string length

SYNOPSIS

       #include <string.h>

       size_t strlen(const char *s);

DESCRIPTION

       The  strlen()  function shall compute the number of bytes in the string to which s points,
       not including the terminating null byte.

RETURN VALUE

       The strlen() function shall return the length of s; no return value shall be  reserved  to
       indicate an error.

ERRORS

       No errors are defined.

EXAMPLES

   Getting String Lengths
       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;
              ...
