This function allows an application program to remove an alternate key path from a collection. TPF collection support (TPFCS) will delete the key path from the collection and release all the resources of that key path back to the TPF system.
Format
#include <c$to2.h> long TO2_removeKeyPath (const TO2_PID_PTR pid_ptr, TO2_ENV_PTR env_ptr, const char *name);
Normal Return
The normal return is a positive value.
Error Return
An error return is indicated by a zero. When zero is returned, use the TO2_getErrorCode function to determine the specific error code. For more information, see Error Handling.
The following error codes are common for this function:
TO2_ERROR_ENV
TO2_ERROR_LOCATOR_NOT_FOUND
TO2_ERROR_METHOD
TO2_ERROR_NOT_INIT
TO2_ERROR_PID
TO2_ERROR_RESERVED_NAME
TO2_ERROR_ZERO_PID
Programming Considerations
Examples
The following example removes the specified key path from the collection.
#include <c$to2.h> /* TO2 API function prototypes */ #include <stdio.h> /* APIs for standard I/O functions */ TO2_ENV_PTR env_ptr; /* Pointer to TO2 Environment */ TO2_PID keyset; char name="fieldA"; /* name of key path to remove */

if (TO2_removeKeyPath(&keyset, env_ptr, name) == TO2_ERROR) { printf("TO2_removeKeyPath failed!\n"); process_error(env_ptr); } else { printf("TO2_removeKeyPath was successful!\n"); }
