StrLenA (FUN) ¶ FUNCTION StrLenA : UDINT 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 0 and eError = ERROR.INVALID_PARAMETER if the given pointer to String is equal NULL InOut: Scope Name Type Comment Return StrLenA UDINT Input pstData CharBufferPtr simply a pointer to byte Output eError ERROR

StrLenW (FUN) ¶ FUNCTION StrLenW : UDINT 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-WStrings or with strings coming from external functions. It will return 0 and eError = ERROR.INVALID_PARAMETER if the given pointer to String is equal NULL InOut: Scope Name Type Comment Return StrLenW UDINT Input pstData CharBufferPtr simply a pointer to byte Output eError ERROR

StrMidA (FUN) ¶ FUNCTION StrMidA : ERROR 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 Return StrMidA ERROR Input pst POINTER TO BYTE udiLength UDINT udiPosition UDINT pstResult POINTER TO BYTE The buffer, where the result will be returned udiResultBufferSize UDINT The size of the buffer (in bytes), where the result will be returned

StrReplaceW (FUN) ¶ FUNCTION StrReplaceW Replaces <iLengthToReplace> wcharacters of pstInput by pstReplaceWith, starting at the <iPosition>-th wcharacter position iPosition = 1 is the first character. InOut: Scope Name Type Comment Input pstInput POINTER TO WSTRING(255) udiInputBufferSize UDINT The size of the buffer, where pstInput points to pstReplaceWith POINTER TO WSTRING(255) udiLengthInput UDINT udiLengthToReplace UDINT udiLengthToReplaceWith UDINT udiPosition UDINT

StrToUpperA (FUN) ¶ FUNCTION StrToUpperA : ERROR Converts all letters to upper case. InOut: Scope Name Type Comment Return StrToUpperA ERROR Input pString CharBufferPtr Pointer to the string.
