[bdc08c1] | 140 | <para>These files constitute the main C library. The C Library is a
|
---|
| 141 | collection of commonly used functions in programs.
|
---|
[58484755] | 142 | This way a programmer doesn't need to create his own functions for every
|
---|
[7d90bd3] | 143 | single task. The most common things like writing a string to the screen
|
---|
[b822811] | 144 | are already present and at the disposal of the programmer.</para>
|
---|
[6370fa6] | 145 |
|
---|
[b822811] | 146 | <para>The C library (actually almost every library) come in two flavors:
|
---|
[6370fa6] | 147 | dynamic ones and static ones. In short when a program uses a static C
|
---|
| 148 | library, the code from the C library will be copied into the executable
|
---|
| 149 | file. When a program uses a dynamic library, that executable will not
|
---|
| 150 | contain the code from the C library, but instead a routine that loads
|
---|
| 151 | the functions from the library at the time the program is run. This
|
---|
[bdc08c1] | 152 | means a significant decrease in the file size of a program. The
|
---|
[08463b5b] | 153 | documentation that comes with the C Library describes this in more
|
---|
[bdc08c1] | 154 | detail, as it is too complicated to explain here in one or two
