Compares a specified number of characters from the beginning of two strings using C run-time (ASCII) collation rules. The comparison is not case-sensitive.
int StrCmpNICA( LPCSTR pszStr1, LPCSTR pszStr2, int nChar );
A pointer to the first null-terminated string to be compared.
A pointer to the second null-terminated string to be compared.
The number of characters from the beginning of each string to be compared.
Returns zero if the substrings are identical. Returns a positive value if the string taken from that pointed to by pszStr1 is alphabetically greater the string taken from that pointed to by pszStr2. Returns a negative value if the string taken from that pointed to by pszStr1 is alphabetically less than the string taken from that pointed to by pszStr2.
Note that StrCmpNIC was designed for comparing canonical strings. These strings are not localized and consist only of characters below ASCII value 128. Therefore, it will not function correctly with a double-byte character set (DBCS) or other multiple-character data.
This function locates the first unequal characters and returns a positive number if the character from the first string is greater than the character from the second, a negative number if it is less, or zero if they are equal. For example, suppose that pszStr1="abczb", pszStr2="abcdefg", and you are comparing the first four characters from each. StrCmpNIC determines that the first unequal character is at position four ("z" in pszStr1 and "d" in pszStr2) and returns a positive value since the ASCII code for "z" is greater than the ASCII code for "d".
For those versions of Windows that do not include StrCmpNIC in Shlwapi.h, this function's individual ANSI or Unicode version must be called directly from Shlwapi.dll. StrCmpNICA is ordinal 153 and StrCmpNICW is ordinal 154.
