strncmp
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Compare two strings, up to a specified number of characters.
<string.h>
int strncmp(const char *s1, const char *s2,
s1
s2
n
Returns a positive number if s1 is greater than s2, zero if s1 is equal to
s2, or a negative number if s1 is less than s2.
strncmp returns a value based on the first character that differs
between s1 and s2. Characters that follow a null character are not
compared.
