strlen

strlen(3)						     Library Functions Manual							 strlen(3)

NAME

       strlen - Finds the length of a string

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <string.h>

       size_t strlen(	   const char *s);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       strlen():  ISO C, XPG4

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies the string.

DESCRIPTION

       The strlen() function returns the number of bytes in the string pointed to by the s parameter. The string length value does not include the
       terminating null character.

									  Note
       If you pass a NULL pointer as the const char * parameter to the strlen function, the function generates a segmentation violation.  To avoid
       the  segmentation violation and cause the function to return 0 (zero), change the NULL pointer treatment for the process before issuing the
       call to the strlen function, as follows: Include the system header file sys/uswitch.h.  Call the uswitch  function,  as	described  in  the
       uswitch(2) reference page.

       The following program illustrates this procedure:

       #include <stdio.h> #include <sys/types.h> #include <sys/uswitch.h>

       main() {
	       size_t  retval;
	       int     uswitch_val;

	       uswitch_val = uswitch(USC_GET,0);
	       uswitch(USC_SET, uswitch_val | USW_NULLP);
	       retval = strlen(NULL);

RETURN VALUES

       On  successful  completion,  the  strlen() function returns the number of characters (bytes) in the string to which the s parameter points.
       Current industry standards specify that no value be reserved to indicate an error.
