Compares a specified number of characters from two strings, ignoring case.

Library:LibC
Classification:ANSI
Service:Characters and Strings

Syntax

  #include <string.h> 
   
  int strncasecmp (
     const char  *s1,   
     const char  *s2,
     size_t       n);

Parameters

s1

(IN) Points to the first string to compare.

s2

(IN) Points to the second string to compare.

n

(IN) Specifies the number of characters to compare.

Return Values

Returns 0 if the two strings match. Otherwise, returns an integer less than or greater than 0, depending on whether s1 is lexicographically less than or greater than s2.

Remarks

The strncasecmp function is identical to strncmp, except that the characters of each string are converted to lowercase before comparison.

Each character is treated as if it is of type unsigned char, and NULL pointers are treated as pointers to empty strings.
