External functions

To the library included range of external functions of the object TSYS of the OpenSCADA core to make simply and unified of the internal operations range:

• int64_t curTime( clockid_t clc = CLOCK_REALTIME ); — Current time in microseconds for the clock clc, from the Unix epoch (01.01.1970) for the CLOCK_REALTIME.
• string int2str( int val ); — Conversion the signed integer to string into the decimal representing.
• int str2int( const string &val ); — Conversion the string value val to the signed integer into the decimal, hexadecimal or octal representing.
• string uint2str( unsigned val ); — Conversion the unsigned integer to string into the decimal representing.
• unsigned long str2uint( const string &val ); — Conversion the string value val to the unsigned integer into the decimal, hexadecimal or octal representing.
• string ll2str( int64_t val ); — Conversion the signed long integer (64bit) to string into the decimal representing.
• string real2str( double val, int prec = 15, char tp = 'g' ); — Conversion the real value in double precision with precision prec of signs and type tp to string.
• double str2real( const string &val ); — Conversion the string value val to the real value.
• string strParse( const string &path, int level, const string &sep, int *off = NULL, bool mergeSepSymb = false ); — String path parsing to the components, which separated by sep, in single symbols merging mergeSepSymb, starting from the offset off and with control to the item's offset end in it.
• string strLine( const string &str, int level, int *off = NULL ); — Multiline text parsing to separate lines, starting from the offset off and with control to the item's offset end in it.
• string strMess( const char *fmt, ... ); — String forming by the template fmt and the arguments, implemented on the basis of "sprintf".
