strlen
Synopsis
#include <string.h>
size_t strlen(const char *s);
size_t strnlen(const char *s, size_t maxlen);
Status
Partially implemented
Conformance
IEEE Std 1003.1-2017
Description
The strlen() function shall compute the number of bytes in the string to which s points, not including the
terminating NUL character.
The
strnlen() function shall compute the smallest of the number of bytes in the array to which s points, not including
any terminating NUL character, or the value of the maxlen argument. The strnlen() function shall never examine
more than maxlen bytes of the array pointed to by s.
Return value
The strlen() function shall return the length of s; no return value shall be reserved to indicate an error.
The
strnlen() function shall return the number of bytes preceding the first null byte in the array to which s points, if
s contains a null byte within the first maxlen bytes; otherwise, it shall return maxlen.
Errors
No errors are defined.
