void* memchr( const void* ptr, int ch, size_t count );
Finds the first occurrence of
ch (after conversion to unsigned char as if by (unsigned char)ch) in the initial
count characters (each interpreted as unsigned char) of the object pointed to by
The behavior is undefined if access occurs beyond the end of the array searched. The behavior is undefined if
ptr is a null pointer.
This function behaves as if it reads the characters sequentially and stops as soon as a matching character is found: if the array pointed to by
|ptr||-||pointer to the object to be examined|
|ch||-||character to search for|
|count||-||max number of characters to examine|
