epicsExportRegistrar ( iocstringtestRegister )

static void iocstringiftest	(	const char *	resultvar,
		const char *	lhs,
		int	operation,
		const char *	rhs
	)

static

Compares the given strings based on the operation flag, putting the result in two different macros.

This function will create two macros called IFresultvar and IFNOTresultvar. If the comparison is true a '#' will be placed in IFNOTresultvar. If the comparison is false a '#' will be placed in IFresultvar.

E.g. to check if a macro named DO_I_EXIST does actually exist then do some follow up:

*               stringtest("EXISTS", "$(DO_I_EXIST)")
*               $(IFEXISTS) < st-existing.cmd
*               $(IFNOTEXISTS) < st-not-existing.cmd
*  

to check a macro named AM_I_CORRECT is equal to CORRECT_ANSWER then do some follow up:

*               stringtest("EXPECTED", "$(AM_I_CORRECT)", 5, "CORRECT_ANSWER")
*               $(IFEXPECTED) < st-expected.cmd
*               $(IFNOTEXPECTED) < st-not-expected.cmd
*  

Parameters

[in]	resultvar	The name of the macro to put the result of the calculation into.
[in]	lhs	The left hand side argument.
[in]	operation	The operation to perform on the string. 0x1: verbose 0x2: strlen(lhs) > 0 (default) 0x4: lhs == rhs 0x8: reverse the above logic
[in]	rhs	The right hand side argument.

static void iocstringtest	(	const char *	resultvar,
		const char *	lhs,
		int	operation,
		const char *	rhs
	)

static

Compares the given strings based on the operation flag and returns ' ' on true and '#' on false into the resultvar macro.

E.g. to check if a macro named DO_I_EXIST does actually exist and put the result in a macro called EXISTS:

* stringtest("EXISTS", "$(DO_I_EXIST)")

*

Parameters

[in]	resultvar	The name of the macro to put the result of the calculation into.
[in]	lhs	The left hand side argument.
[in]	operation	The operation to perform on the string. 0x1: verbose 0x2: strlen(lhs) > 0 (default) 0x4: lhs == rhs 0x8: reverse the above logic
[in]	rhs	The right hand side argument.
