MEMCHR
Synopsis
Description
The memchr() function is similar to strchr() except that instead of searching null terminated strings,
it searches a block of memory specified by length for a particular byte. Its arguments are a pointer
to the memory to be searched, the value of the byte to be searched for, and the length of the block.
A pointer to the first occurrence of that byte in the block is returned.
Example
210
#include <string.h>
/* For baseline and midrange processors */
const void * memchr (const void * block, int val, size_t length)
/* For high-end processors */
void * memchr (const void * block, int val, size_t length)
#include <string.h>
#include <stdio.h>
unsigned int ary[] = {1, 5, 0x6789, 0x23};
void
main (void)
{
}
char * cp;
cp = memchr(ary, 0x89, sizeof ary);
if(!cp)
else
printf("not found\n");
printf("Found at offset %u\n", cp - (char *)ary);
