    raylib API parser

    This parser scans raylib.h to get API information about structs, enums, functions and defines.
    All data is divided into pieces, usually as strings. The following types are used for data:

     - struct FunctionInfo
     - struct StructInfo
     - struct EnumInfo
     - struct DefInfo

    CONSTRAINTS:

    This parser is specifically designed to work with raylib.h, so, it has some constraints:

     - Functions are expected as a single line with the following structure:

       <retType> <name>(<paramType[0]> <paramName[0]>, <paramType[1]> <paramName[1]>);  <desc>

       Be careful with functions broken into several lines, it breaks the process!

     - Structures are expected as several lines with the following form:

       <desc>
       typedef struct <name> {
           <fieldType[0]> <fieldName[0]>;  <fieldDesc[0]>
           <fieldType[1]> <fieldName[1]>;  <fieldDesc[1]>
           <fieldType[2]> <fieldName[2]>;  <fieldDesc[2]>
       } <name>;

     - Enums are expected as several lines with the following form:

       <desc>
       typedef enum {
           <valueName[0]> = <valueInteger[0]>, <valueDesc[0]>
           <valueName[1]>,
           <valueName[2]>, <valueDesc[2]>
           <valueName[3]>  <valueDesc[3]>
       } <name>;

       NOTE: Multiple options are supported for enums:
          - If value is not provided, (<valueInteger[i -1]> + 1) is assigned
          - Value description can be provided or not

    OTHER NOTES:

     - This parser could work with other C header files if mentioned constraints are followed.

     - This parser does not require <string.h> library, all data is parsed directly from char buffers.
