_strnset, _wcsnset, _mbsnset

Initialize characters of a string to a given format.

char*_strnset(char*string,intc**,size_tcount);**

wchar_t*_wcsnset(wchar_t*string,wchar_tc**,size_tcount);**

unsignedchar*_mbsnset(unsignedchar*string,unsignedintc**,size_tcount);**

For additional compatibility information, see Compatibility in the Introduction.

Libraries

Return Value

Each of these functions returns a pointer to the altered string.

Parameters

string

String to be altered

c

Character setting

count

Number of characters to be set

Remarks

The _strnset function sets, at most, the first count characters of string to c (converted to char). If count is greater than the length of string, the length of string is used instead of count.

_wcsnset and _mbsnset are wide-character and multibyte-character versions of _strnset. The string arguments and return value of _wcsnset are wide-character strings; those of _mbsnset are multibyte-character strings. These three functions behave identically otherwise.

Generic-Text Routine Mappings

Example

/* STRNSET.C */

#include <string.h>
#include <stdio.h>

void main( void )
{
   char string[15] = "This is a test";
   /* Set not more than 4 characters of string to be *'s */
   printf( "Before: %s\n", string );
   _strnset( string, '*', 4 );
   printf( "After:  %s\n", string );
}

Output

Before: This is a test
After:  **** is a test
