PxConfigDelete

Arguments

Returns

-1 if the entry or section was deleted or doesn't exist, or 0 on failure.

Description

These functions delete configuration entries or whole sections. The configuration file must first be opened with a call to PxConfigOpen with the mode set to PXCONFIG_WRITE. PxConfigDeleteSection deletes all entries of the section up to the beginning of the next section or the end of the file, and clears the internal current section.

Example

This example, ex_PxConfigDelete.g, and its configuration file (configtest.txt) are included in the product distribution. A copy of the configtext.txt configuration file is shown in the PxConfigRead reference page.
