The strcoll () function in C
The function int strcoll (const char * str1, const char * str2) compares strings str1 and str2. The result depends on setting LC_COLLATE.
Declaring the strcoll () function in C
Here is the declaration for strcoll () in C:
int strcoll ( const char * str1 , const char * str2 )
Parameters
str1 - This is the first string to be compared.
str2 - This is the second string to be compared.
Returns the value
This function returns the following values:
If the value returns <0, this function indicates that str1 is shorter than str2.
If the value returns> 0, this function indicates that str2 is shorter than str1.
If the return value = 0, this function indicates that str1 is equal to str2.
For example
The following C program illustrates the usage of strcoll () in C:
#include #include int main () { char str1 [ 15 ]; char str2 [ 15 ]; int ret ; strcpy ( str1 , "abc" ); strcpy ( str2 , "ABC" ); ret = strcoll ( str1 , str2 ); if ( ret > 0 ) { printf ( "Chuoi str1 la ngan hon chuoi str2" ); } else if ( ret < 0 ) { printf ( "Chuoi str2 la ngan hon chuoi str1" ); } else { printf ( "Chuoi str1 la bang chuoi str2" ); } return ( 0 ); }
