NAME
strlen, strnlen -- find length of string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h> size_t strlen(const char *s); size_t strnlen(const char *s, size_t maxlen);
DESCRIPTION
The strlen() function computes the length of the string s. The strnlen() function attempts to compute the length of s, but never scans beyond the first maxlen bytes of s.
RETURN VALUES
The strlen() function returns the number of characters that precede the terminating NUL character. The strnlen() function returns either the same result as strlen() or maxlen, whichever is smaller.
SEE ALSO
