strcoll

Compares two strings and returns an integer that indicates if the strings differ and how they differ. The function uses the collating information in the LC_COLLATE category of the current locale to determine how the comparison is performed.

Format 

#include  <string.h>

int strcoll  (const char *s1, const char *s2);

Arguments

s1, s2
Pointers to character strings.

Description

This function, unlike strcmp, compares two strings in a locale-dependent manner. Because no value is reserved for error indication, the application must check for one by setting errno to 0 before the function call and testing it after the call.

See also the strxfrm function is this section.

Return Values
< 0  Indicates that s1 is less than s2. 
= 0  Indicates that the strings are equal. 
> 0  Indicates that s1 is greater than s2.
