Built-in Functions
iresult=memcmp( m1 , m2 , n )
ptr=memchr( m1 , c , n )
ptr=strerror(errnum)
Compare m1 to m2 (n bytes)
Find c in first n characters of m1 and return
&m1[i]
Maps the error number in errnum to an error
message string. The parameters 'errnum' is an
unsigned 8 bit int. Returns a pointer to the
string.
Parameters: s1 and s2 are pointers to an array of characters (or the name of an array). Note
that s1 and s2 MAY NOT BE A CONSTANT (like "hi").
n is a count of the maximum number of character to operate on.
c is a 8 bit character
m1 and m2 are pointers to memory.
Returns:
Function:
ptr is a copy of the s1 pointer
iresult is an 8 bit int
result is -1 (less than), 0 (equal) or 1 (greater than)
res is an integer.
Functions are identified above.
