strlen(D3) strlen(D3)
NAME
strlen - determine the length of a string
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
size_t strlen (const char *sptr)
Arguments
The argument sptr points to a string, which is an array of
characters terminated by a null-character.
DESCRIPTION
The function strlen determines the length of characters in the
string pointed to by sptr.
Return Values
The function strlen returns the number of characters, not
including the terminating null-character, in the string
pointed to by sptr.
USAGE
strlen is often used to determine the length of a string prior
to allocating space to hold a copy of the string. In this
case, remember to allocate one more byte than the size
returned by strlen, to hold the null-character.
Level
Base or Interrupt.
Synchronization Constraints
Does not sleep.
Driver-defined basic locks, read/write locks, and sleep locks
may be held across calls to this function.
