Function Documentation

◆ acpUtilStrToAchar()

achar* acpUtilStrToAchar	(	void *	vpMem,
		const char *	cpStr,
		aint *	uipLen
	)

Convert a null-terminated ASCII string to an array of achar characters.

This function will allocate memory for the array, relieving the caller of the allocation burden. The allocated memory may be freed with vMemFree( acpBuf ), where acpBuf is the returned pointer. However, the allocated memory will also be freed with vMemDtor() which every application should call for memory clean up anyway.

Parameters

vpMem	Pointer to a memory context returned from vpMemCtor();
cpStr	Pointer to the null-terminated string to convert.
uipLen	Pointer to an unsigned integer to receive the number of characters in the converted achar array.

Returns: Returns a pointer to the converted achar array. Returns the number of characters in the array if uipLen != NULL.

Definition at line 824 of file utilities.c.

◆ bUtilAstToXml()

abool bUtilAstToXml	(	void *	vpAst,
		char *	cpType,
		const char *	cpFileName
	)

Convert the AST records to XML format.

Parameters

vpAst	Pointer to a valid AST context previously returned from vpAstCtor(). If not valid application will silently exit with a BAD_CONTEXT exit code.
cpType	Select the character type for the parsed phrases: "u" or "U" for Unicode "h" or "H" for hexadecimal characters "d" or "D" for decimal characters default (NULL or none of the above) decimal characters
cpFileName	Name of the file to convert to. If NULL, stdout is used.

Definition at line 1126 of file utilities.c.

◆ bUtilCompareFileLines()

abool bUtilCompareFileLines	(	void *	vpMem,
		const char *	cpFileL,
		const char *	cpFileR
	)

Compare two text files, line by line, without regard for the line ending characters.

Developed for the problem of comparing files which are identical except for the line end characters. Necessitated by the different line ending conventions of different OSs.

Parameters

vpMem	Pointer to a valid memory context previously returned from vMemCtor(). If invalid the application will silently exit with a BAD_CONTEXT exit code.
cpFileL	Left file name.
cpFileR	Right file name.

Returns: True if all lines are identical. False otherwise.

Definition at line 350 of file utilities.c.

◆ bUtilCompareFiles()

abool bUtilCompareFiles	(	const char *	cpFileL,
		const char *	cpFileR
	)

Compare two files, byte for byte.

Parameters

cpFileL	Pointer to left file name.
cpFileR	Pointer to right file name.

Returns: True if both files are byte-for-byte equal. False if not equal or if either file does not exist or otherwise cannot be opened.

Definition at line 306 of file utilities.c.

◆ cpUtilAcharToStr()

const char* cpUtilAcharToStr	(	void *	vpMem,
		achar *	acpAchar,
		aint	uiLen
	)

Convert an array of achar characters to a null-terminated ASCII string.

Any achar characters that are not valid printing ASCII characters will be represented with a period ('.' or 46).

This function will allocate memory for the string, relieving the caller of the allocation burden. The allocated memory may be freed with vMemFree(cpStr), where cpStr is the returned pointer. However, the allocated memory will also be freed with vMemDtor() which every application should call for memory clean up anyway.

Parameters

vpMem	Pointer to a memory context returned from vpMemCtor();
acpAchar	Pointer to an achar array to convert. May not be NULL.
uiLen	The number of characters in the acpAchar array.

Returns: Returns a pointer to the converted, null-terminated string.

Definition at line 857 of file utilities.c.

◆ cpUtilOpName()

const char* cpUtilOpName ( aint uiId )

Parameters

uiId	The opcode identifier to convert.

	)

Convert an u32_phrase to a null-terminated ASCII string.

Any u32_phrase characters that are not valid printing ASCII characters will be represented with a period ('.' or 46).

This function will allocate memory for the string, relieving the caller of the allocation burden. For a simpler solution with less overhead but with risk of buffer overrun, see cpPhraseToStr() in tools.c. The allocated memory may be freed with vMemFree(cpStr), where cpStr is the returned pointer. However, the allocated memory will also be freed with vMemDtor() which every application should call for memory clean up anyway.

Parameters

vpMem	Pointer to a memory context returned from vpMemCtor();

cpString	Pointer to a null-terminated string whose line ends to translate. May not be NULL or empty.
cpEnd	Pointer to a null-terminated string of characters to add to the end of each line. NOTE: Normally this will be one of the common line ending strings, "\\r\\n", "\\n" or "\\r". However, there is no restriction here. Any string can be used. If NULL or empty, all line endings in the input string will be removed.
cpFileName	Name of the converted file. If NULL, stdout is used.

Definition at line 1228 of file utilities.c.

◆ vUtilCurrentWorkingDirectory()

void vUtilCurrentWorkingDirectory ( void )

◆ vUtilFileRead()

void vUtilFileRead	(	void *	vpMem,
		const char *	cpFileName,
		uint8_t *	ucpData,
		aint *	uipLen
	)

Read a file into the caller's data area.

Parameters

	vpMem	Pointer to a valid memory context previously returned from vMemCtor(). If invalid the application will silently exit with a BAD_CONTEXT exit code.
	cpFileName	Relative or absolute path name of the file to read into.
	ucpData	Pointer to the caller's 8-bit byte data buffer. If NULL, no data is read.
[in,out]	uipLen	Pointer to the integer to receive the number of bytes in the file. On input, this is the length of the caller's data buffer. Data, up to this length, will be read into the buffer. Regardless of its value on input, it will be set to the actual number of bytes in the file on output. On return, if uipLen is <= its original value then the caller can be confident that all data is in the buffer provided. If uipLen > its original value, then the caller must repeat the call with a larger data buffer.

Returns: Throws exception on file open or read error.

Definition at line 252 of file utilities.c.
