Detailed Description

implementation of the main memory management in paceval

implementation of the data types, objects and classes required in paceval that are responsible for memory management (e.g. paceval_cRegisteredObject and paceval_cCleanupHandler) and error handling (e.g. paceval_sErrorInformation)

Macro Definition Documentation

paceval_max_logging_buffer

#define paceval_max_logging_buffer   25000

Function Documentation

paceval_deleteLoggingMemory()

bool paceval_deleteLoggingMemory

(

)

deletes the memory buffer used for logging, which empties it

Here is the call graph for this function:

Here is the caller graph for this function:

paceval_getCurrentTime()

unsigned long paceval_getCurrentTime

(

)

gets the current time in milliseconds since the system started

Here is the caller graph for this function:

paceval_identifyOperatorFromMathematicalCharacter()

paceval_eOperatorTypes paceval_identifyOperatorFromMathematicalCharacter

(

paceval_eMathematicalCharacterTypes

eMathematicalCharacterType_in

)

forward declaration - gets the current time in milliseconds since the system started (see paceval_cCleanupHandler.h) identifies the associated type of paceval_eOperatorTypes for a type of paceval_eMathematicalCharacterTypes, e.g. the associated ADDITION_SIGN for ADDITION_CHARACTER (see paceval_cCleanupHandler.cpp)

Parameters

eMathematicalCharacterType_in

specifies the type of paceval_eMathematicalCharacterTypes

Here is the caller graph for this function:

paceval_identifyOperatorFromOperatorType()

void paceval_identifyOperatorFromOperatorType	(	char *	operator_out,
		paceval_eOperatorTypes	eReturnOperator_in )

identifies the operator (e.g. "+") from the type of operator (e.g. ADDITION_SIGN)

Parameters

operator_out	specifies the buffer for the operator
eReturnOperator_in	specifies the type of operator to look for

Here is the call graph for this function:

Here is the caller graph for this function:

paceval_identifyOperatorFromString()

paceval_eOperatorTypes paceval_identifyOperatorFromString	(	const char *	operator_in,
		long	valueNode2_in,
		const char *	valueOperator_in )

identifies the type of operator (e.g. ADDITION_SIGN) based on the associated parameters

Parameters

operator_in	is the character string that contains the operator (e.g. ":=", "+" or "sin")
valueNode2_in	specifies the node of the possible second operand (e.g. the operator "y" for "x+y")
valueOperator_in	specifies the numerical value to convert when ":=<floating point number>" (SET_TO_VALUE_SIGN)

Here is the call graph for this function:

Here is the caller graph for this function:

paceval_lockGlobalVariables()

bool paceval_lockGlobalVariables

(

)

Here is the caller graph for this function:

paceval_setCallbackUserFunctionString()

void paceval_setCallbackUserFunctionString	(	unsigned int	numberUserFunction_in,
		const char *	singleFunctionString_in )

allows the definition of up to 1000 custom user functions (see pacevalLibrary_SetCallbackUserFunction())

Parameters

numberUserFunction_in	specifies the number of the user function to set the single function for (e.g. 1)
singleFunctionString_in	specifies the user-defined single function (e.g. "my_function1")

Here is the caller graph for this function:

paceval_unlockGlobalVariables()

void paceval_unlockGlobalVariables

(

)

Here is the caller graph for this function:

paceval_writeLoggingString()

void paceval_writeLoggingString

(

const char *

loggingString_in

)

writes data for logging with a time stamp into a memory buffer and, if paceval_ENABLE_LOGGING_TO_FILE is set, into the file "paceval_loggingFile.log"

Parameters

loggingString_in

specifies the string to add to logging

Here is the call graph for this function:

Here is the caller graph for this function:

pacevalLibrary_GetLoggingInformation()

int pacevalLibrary_GetLoggingInformation

(

char *

paceval_loggingInformation_out

)

returns the string of the logging information - the return value is the length of the logging string

Parameters

paceval_loggingInformation_out

points to the buffer that will receive the string (set paceval_strVersion_in to NULL to receive the length of the logging string)

Here is the call graph for this function:
