1. Compare string size functions 1) Case Insensitive --- strcasecmp Function prototype: Int strcasecmp (const char * S1, const char * S2 ); Function Description: Used to compare S1 and S2 strings. Differences in Case sensitivity are automatically

4. Deconstruction method Destroy The method generates a lock on the resource and then releases the resource, and finally calls the inherited destroy method to release the Resourcestream. It is implemented as follows: destructor

4. memccpy Prototype: extern void * memccpy (void * dest, void * src, unsigned char ch, unsigned int count ); Usage: # include  Function: the data is copied from the memory area indicated by src to the memory area indicated by dest. If the ch

Function: strcatPrototype:Char * strcat (char * dest, char * src );Function: add the src string to the end of dest (overwrite '\ 0' at the end of dest) and add' \ 0 '.Note: The memory areas specified by src and dest cannot overlap and dest must have

C string function Summary 1. bcmp Prototype: extern int bcmp (const void * S1, const void * S2, int N );Usage: # include Function: Compares the first n Bytes of the string S1 and S2.NOTE: If S1 = S2 or n = 0, zero is returned; otherwise, a non-zero

1. bcmpPrototype: extern int bcmp (const void *S1, const void *s2, int n);Usage: #include Function: Compares the first n bytes of a string S1 and S2 for equalityDescription: Returns 0 for equality, otherwise returns a value other than 02.
