OMmain_init

Synopsis

For UNIX systems:
int_OMmain_init(int argc,char * argv );
For PC systems:
int OMmain_init(HINSTANCE hInst, HINSTANCE hPrevInst,
LPSTR CmdStr, int CmdShow );

Description

OMmain_init initializes the Object Manager. As part of the initialization, object libraries are loaded according to the templ.v file.You call OMmain_init whenever you write your own C or C++ main function.The arguments argc and argv specify command-line arguments. OMmain_init scans for and processes AVS/Express-specific arguments, such as -vcp. This routine notifies you about arguments that it does not understand. You should remove any arguments from argc and argv (or CmdStr for PC's) that are not recognized by AVS/Express before calling this routine.PREinit and BASEinitAs part of using OMmain_init, you must create two functions, PREinit and BASEinit. OMmain_init calls PREinit before loading libraries and BASEinit after loading libraries.You typically either create routines that are empty, or use functions generated for you in processname.c for a particular process.The routines have the following prototypes:void PREinit (int * argc , _char * argv ); void BASEinit (int * argc , _char * argv );Notice that with PREinit and BASEinit the argc parameter is a pointer to an integer.

Arguments

argc

The number of arguments in argv .

argv

The argument vector.

Returned value

A VCP mode that can be submitted to a subsequent call to OMmain_loop. For example, if argv contains the -vcp argument, then OMmain_init returns OM_VCP_PRESENT.

Examples
