Synopsis

Releases memory occupied by a string. Use the mem_strfree() macro to call this function! Call this function to free strings allocated using mem strdup (). Accepts the address of a char pointer as argument: if the pointer is not null, the string is freed, and the pointer is set to null. Returns the address of the modified pointer.

Examples

    char
        *string1 = NULL,
        *string2 = NULL;
    string1 = mem_strdup ("This is a string");
    mem_strfree (&string1);
    mem_strfree (&string2);
