Arguments:
Return Value:
Remarks:
Example:
string.h
The type of the result of the sizeof operator.
<string.h>
The value of a null pointer constant.
<string.h>
Locates a character in a buffer.
<string.h>
void *memchr(const void *s, int c, size_t n);
s
c
n
Returns a pointer to the location of the match if successful; otherwise,
returns null.
memchr stops when it finds the first occurrence of c or after searching
n number of characters.
