Initializes the Grid API.
Syntax
ESSG_FUNC_M EssGInit (pInitStruct, pHandle);
Parameter | Data Type | Description |
---|---|---|
pInitStruct | ESSG_INIT_T | Pointer to a structure containing useful information for the EGAPI. |
pHandle | ESSG_PHANDLE_T | Pointer to the handle sent back from the EGAPI. |
Notes
Required before calling all other EGAPI functions except for EssGVersion.
Make this call only once at the beginning of a session.
This function returns a handle, which you must pass to EssGNewGrid for each grid being used, and to any other EGAPI call requiring a non-grid specific handle.
A thread may require its own handle (pHandle) to avoid overwriting another thread's networking status information.
Return Value
If successful, returns ESSG_STS_NOERR.
Access
None.
Example
#include <essapin.h> #include <essgapin.h> ESSG_FUNC_M sts = ESS_STS_NOERR; ESSG_INIT_T InitStruct; ESSG_HANDLE_T Handle; InitStruct.ulVersion = ESSG_VERSION; InitStruct.ulMaxRows = 1000; InitStruct.ulMaxColumns = 200; InitStruct.pfnMessageFunc = ESS_NULL; InitStruct.pUserdata = ESS_NULL; sts = EssGInit(&InitStruct, &Handle);
