In C, the functions strcmp and memcmp perform a three-way comparison between strings and memory buffers, respectively. They return a negative number when the first argument is lexicographically smaller than the second, zero when the arguments are equal, and a positive number otherwise.
Most of the functions that operate on C strings are declared in the string.h header (cstring in C++), while functions that operate on C wide strings are declared in the wchar.h header (cwchar in C++). These headers also contain declarations of functions used for handling memory buffers; the name is thus something of a misnomer.
There is no standard trim function in C or C++. Most of the available string libraries [55] for C contain code which implements trimming, or functions that significantly ease an efficient implementation. The function has also often been called EatWhitespace in some non-standard C libraries.
C lacks this feature and the localization of variables or functions can be done only for a compiling module wherein the variables or functions would have been declared static. C and Pascal allow functions to be indirectly invoked through a function pointer. In the following example, the statement (*cmpar)(s1, s2) is equivalent to strcmp(s1, s2):
In this file, there are two functions sin() and strcmp(), a global variable Foo, and two constants STATUS and VERSION.When SWIG creates an extension module, these declarations are accessible as scripting language functions, variables, and constants respectively.
For example, the C function strcmp performs a three-way comparison and returns −1, 0, or 1 according to this convention, and qsort expects the comparison function to return values according to this convention.
