Macro Definition Documentation

◆ SBG_STRING_INTERNAL_BUFFER_MIN_SIZE

#define SBG_STRING_INTERNAL_BUFFER_MIN_SIZE (4)

Minimum size of the internal buffer, in bytes.

This constant must be strictly positive in order to guarantee that no errors can occur during the construction of an empty string.

◆ SBG_STRING_INTERNAL_BUFFER_DEFAULT_SIZE

#define SBG_STRING_INTERNAL_BUFFER_DEFAULT_SIZE (16)

Default size of the internal buffer, in bytes.

Typedef Documentation

◆ SbgString

typedef struct _SbgString SbgString

String.

The buffer contains a C null-terminated string. The null-terminating character is not considered to be part of the string content.

Attempts to modify a read-only string lead to undefined behavior.

Attempts to modify a string while the last modification operation error is set are canceled and return the last error code.

◆ SbgStringIterator

typedef struct _SbgStringIterator SbgStringIterator

String iterator.

Function Documentation

◆ sbgStringConstructEmpty()

SBG_COMMON_LIB_API void sbgStringConstructEmpty ( SbgString * pString )

String constructor.

The rationale for this constructor is to guarantee that no errors may occur on the construction of empty strings.

Parameters

[in] pString String.

◆ sbgStringConstruct()

SBG_COMMON_LIB_API SbgErrorCode sbgStringConstruct	(	SbgString *	pString,
		const SbgString *	pSourceString
	)

The string content is initialized from the given source string. If that string is NULL, the string is initialized with an empty content.

Parameters

[in]	pString	String.
[in]	pSourceString	Source string, may be NULL.

Returns: SBG_NO_ERROR if successful.

◆ sbgStringConstructCString()

SBG_COMMON_LIB_API SbgErrorCode sbgStringConstructCString	(	SbgString *	pString,
		const char *	pCString
	)

String constructor.

The string content is initialized from the given C null-terminated string.

Parameters

[in]	pString	String.
[in]	pCString	C null-terminated string.

Returns: SBG_NO_ERROR if successful.

◆ sbgStringConstructVF()

SBG_COMMON_LIB_API SbgErrorCode sbgStringConstructVF	(	SbgString *	pString,
		const char *	pFormat,
		va_list	args
	)

String constructor.

The string content is initialized from formatted data from a variable argument list.

Parameters

[in]	pString	String.
[in]	pFormat	Format.

SBG_COMMON_LIB_API SbgErrorCode SBG_COMMON_LIB_API SbgErrorCode sbgStringConstructF	(	SbgString *	pString,
		const char *	pFormat,
			...
	)

String constructor.

The string content is initialized from formatted data.

Parameters

		char *	pBuffer,
		size_t	size
	)

String constructor.

The string content is initialized from the given C null-terminated string.

If the C null-terminated string is NULL then the string contains the content of the given buffer before construction. In this case the content of the given buffer must be a C null-terminated string.

The given buffer is owned by the string and must not be modified while the string is in use. After destroying the string, the buffer contains the content of the string immediately before destruction.

Parameters

Parameters

[in]	pIterator	String iterator.
[in]	pSeparators	C null-terminated string containing separator characters.

Safely copy source string to destination according to destination provided buffer size.

This method tends to replace strncpy where you would like to safely copy a string with buffer overflow checking. If the provided output buffer is too small, the method will return a valid NULL terminated C string in destination. This condition will be returned using SBG_BUFFER_OVERFLOW error code.

Parameters

[out]	pDestination	The destination string that should hold the copied input string.
[in]	pSource	The source NULL terminated C string to copy to the destination.
[in]	destMaxSize	The destination buffer size including the null terminating char.

Returns: SBG_NO_ERROR if the source string has been copied to destination SBG_BUFFER_OVERFLOW if the destination is too small to hold the source string.

◆ sbgStringFirstValidChar()

SBG_COMMON_LIB_API const char* sbgStringFirstValidChar ( const char * pInputStr )

Skip all spacing characters from the beginning of a string.

Parameters

[in] pInputStr Pointer on a read only string to trim.

Returns: Pointer to the first useful char.
