Additions:
**Note:** In order to make calling the C runtime functions very easy, any string type argument may be directly passed to a procedure referring to a parameter declared as 'zstring ptr'. The compiler performs itself an automatic conversion (without warning message) between any string type argument and the 'zstring ptr' type parameter.

The Include File column contains the name of the file which you must include, using the ##[[KeyPgInclude|#include]]## directive at the beginning of your program. If you don't include the appropriate include file, the program either will not compile, or it will compile apparently correctly but give incorrect results when run. All of the C Runtime headers are located in the ##crt## directory; for example, if the specified header is ##math.bi##, use ###include "crt/math.bi"## or ###include "crt\math.bi"##, our just ###include "crt.bi"## including all the others.

The Comments column contains a very brief description of the use of the function. The list is not complete, however it provides information on the major functions in the C Runtime Library. It should, at the very least, indicate what functions are available in the standard C library allow you to do more investigation on your own. Some of the C library functions documented elsewhere may not be available in ""FreeBASIC"". Check the appropriate include file for more information.
**Note:** The following prototypes are not the official ""FreeBASIC"" prototypes (see the include files), however, they will give you enough information to properly use the functions.
The Include File column contains the name of the file which you must include, using the ##[[KeyPgInclude #include]]## directive at the beginning of your program. If you don't include the appropriate include file, the program either will not compile, or it will compile apparently correctly but give incorrect results when run.
