StrConcatA (FUN) ¶ FUNCTION StrConcatA : BOOL This function concatenates pstFrom to pstTo if the iBufferSize from pstTo is big enough. The function will do its work either with native IEC-Strings or with strings coming from external functions. It will return FALSE and does no concatenation if one of the strings is NULL or the buffer size is not big enough. InOut: Scope Name Type Comment Return StrConcatA BOOL Input pstFrom CharBufferPtr simply a pointer to byte pstTo CharBufferPtr simply a pointer to byte iBufferSize INT the buffer size of pstTo

StrCpyA (FUN) ¶ FUNCTION StrCpyA : DINT Does a strcpy from the source string pStr to the buffer pBuffer. pBuffer must not be NULL! Will return the number of copied characters including the terminating ‘\0’ or “\0” InOut: Scope Name Type Comment Return StrCpyA DINT Input pBuffer CharBufferPtr iBufferSize DINT the size in bytes of the buffer pStr CharBufferPtr the source as a pointer to string

StrDeleteA (FUN) ¶ FUNCTION StrDeleteA Deletes <iLength> characters of <pwst>, beginning at the <iPosition>-th character position. <iPosition> = 1 is the first character. This function has been adapted from StrDeleteW InOut: Scope Name Type Input pby POINTER TO BYTE iLength INT iPosition INT

StrFindA (FUN) ¶ FUNCTION StrFindA : INT Similar semantics as Find from the standard.library. A null pointer will lead to a return of -1 InOut: Scope Name Type Comment Return StrFindA INT Input pst1 POINTER TO STRING(255) pst2 POINTER TO STRING(255) uiSearchStart UINT a position relative to 1, where the search starts

StrIsNullOrEmptyA (FUN) ¶ FUNCTION StrIsNullOrEmptyA : BOOL This function determines if the given string is null or empty InOut: Scope Name Type Comment Return StrIsNullOrEmptyA BOOL Input pstData CharBufferPtr simply a pointer to byte

StrLenA (FUN) ¶ FUNCTION StrLenA : DINT This function determines the length of a string by searching for a terminating zero character. The function will do its work either with native IEC-Strings or with strings coming from external functions. It will return -1 if the given pointer to String is equal NULL InOut: Scope Name Type Comment Return StrLenA DINT Input pstData CharBufferPtr simply a pointer to byte

StrMidA (FUN) ¶ FUNCTION StrMidA Return <iLength> characters of <pst>, beginning at the <iPosition>-th character position. <iPosition> = 1 is the first character. This function has been adapted from StrMidW InOut: Scope Name Type Comment Input pst POINTER TO BYTE uiInputBufferSize UINT The size of the buffer, where pwst points to iLength INT iPosition INT pstResult POINTER TO BYTE The buffer, where the result will be returned uiResultBufferSize UINT The size of the buffer (in bytes), where the result will be returned

StrPadLeftA (FUN) ¶ FUNCTION StrPadLeftA : BOOL This function generate a padding string and concatenates it with pstFrom to pstTo if the iBufferSize from pstTo is big enough. The function will do its work either with native IEC-Strings or with strings coming from external functions. It will return FALSE and does no concatenation if one of the strings is NULL or the buffer size is not big enough. InOut: Scope Name Type Comment Return StrPadLeftA BOOL Input byPadChar BYTE The padding character filling the space from left pstFrom CharBufferPtr simply a pointer to byte pstTo CharBufferPtr simply a pointer to byte diBufferSize DINT the buffer size of pstTo

StrPadRightA (FUN) ¶ FUNCTION StrPadRightA : BOOL This function generate a padding string and concatenates it with pstFrom to pstTo if the iBufferSize from pstTo is big enough. The function will do its work either with native IEC-Strings or with strings coming from external functions. It will return FALSE and does no concatenation if one of the strings is NULL or the buffer size is not big enough. InOut: Scope Name Type Comment Return StrPadRightA BOOL Input byPadChar BYTE The padding character filling the space from right pstFrom CharBufferPtr simply a pointer to byte pstTo CharBufferPtr simply a pointer to byte diBufferSize DINT the buffer size of pstTo
