strncoll()

Locale-aware collating string comparison with limited length.

  #include <extras/extras_string.h>
  
  int strncoll(const char *s1, const char *s2, size_t max);    

str1

A pointer to a character string.

str2

A pointer to a character string.

max

The maximum number of characters to compare.

The function performs the comparison according to the collating sequence specified by the LC_COLLATE component of the current locale. The function stops when it has reached a null character in one of the strings or when it has compared max characters.

This function returns one of these values:

• zero if all characters in s1 are identical to and appear in the same order as the characters in s2
• a negative value if the numeric value of first non-matching character in s1 is less than its counterpart in s2
• a positive value if the numeric value of first non-matching character in s1 is greater than its counterpart in s2

This facility is not specified in the ISO/IEC standards. It is an EWL extension of the standard libraries.
