memchr() Find Character in Buffer
#include <memory.h> Required for declarations only
#include <string.h> Use either string.h or memory.h
char *memchr(buf,ch,cnt);
char *buf; Pointer to buffer
int ch; Character to copy
unsigned cnt; Number of characters
memchr() searches 'buf' for the first occurrence of 'ch'. The search
continues until 'ch' is found or 'cnt' bytes have been searched.
Returns: If 'ch' is found, a pointer to the location of 'ch' in
'buf' is returned. NULL is returned if 'ch' is not found
within the first 'cnt' bytes of 'buf'.
Notes: Buffers are arrays of characters and are usually not
terminated with a null character ('\0'). The
buffer-manipulation routines always have a length or
count argument.
-------------------------------- Example ---------------------------------
The following statement finds the first occurrence of 'z' in 'buff'.
#include <memory.h>
char buff[100];
char *bufptr;
main()
{
bufptr = memchr(buffr,'z',100);
}
