Description

uStructSize

Structure size. It should be equal to sizeof(PROGRESSDATA2).

Id

Identifier of the process currently running. For a list of possible values, refer to DOC2_OCRPROCID.

nPercent

Progress of the current process expressed as a percentage.

Comments

pPROGRESSDATA2 is a pointer to a PROGRESSDATA2 structure. If the function parameter type is pPROGRESSDATA2, declare a PROGRESSDATA2 variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pPROGRESSDATA2 variable is necessary only if the program requires a pointer.

This structure will be filled only when PROGRESSCALLBACK2 is called. The PROGRESSCALLBACK2 function will be called if you have set a callback function with L_Doc2SetProgressCB.
