VERSIONINFO

Summary

The VERSIONINFO structure provides information about the LEADTOOLS toolkit.

Syntax

typedef struct _VERSIONINFO 
{ 
   L_UINT uStructSize; 
   L_UCHAR Product[60]; 
   L_INT Level; 
   L_INT MajorNumber; 
   L_INT MinorNumber; 
   L_UCHAR Date[16]; 
   L_UCHAR Time[16]; 
   L_BOOL HasExpireDate; 
} VERSIONINFO, *pVERSIONINFO;

Members

uStructSize

Size of this structure in bytes, for versioning. Use the sizeof() operator to calculate this value.

Product

Product name, expressed as a character string.

Level

Toolkit level. Possible values are:

Value	Meaning
TOOLKIT_LEVEL_DOCUMENT	[0x00] Document Toolkit
TOOLKIT_LEVEL_RASTER	[0x01] Raster Toolkit
TOOLKIT_LEVEL_MEDICAL	[0x02] Medical Toolkit
TOOLKIT_LEVEL_EVAL	[0x03] Evaluation Toolkit
TOOLKIT_LEVEL_NAG	[0x04] Nag Toolkit

MajorNumber

Major version number.

MinorNumber

Minor version number.

Date

Date of the build, expressed as a character string.

Time

Time of the build, expressed as a character string.

HasExpireDate

Flag that determines whether kernel has expiration date. Possible values are:

Value	Meaning
TRUE	Kernel has expiration date.
FALSE	Kernel has no expiration date.

Comments

pVERSIONINFO is a pointer to a VERSIONINFO structure. Where a function parameter type is pVERSIONINFO, you can declare a VERSIONINFO variable and pass the variable's address in the parameter. Declaring a pVERSIONINFO variable is necessary only if your program requires a pointer.

Some functions which take this structure as a parameter require that the structure be initialized prior to the function call. You must set the uStructSize member to the total size, in bytes, of the structure. Use the sizeof() operator to calculate this value. Functions that do not require the structure be initialized will take the total size of the structure, in bytes, as an additional function parameter.
