string
The string module automatically imports the err module.
All the functions are designed to work for the strings in the default encoding. If passed a string in an encoding that has a different null terminator, then the results are undefined and the program will most likely crash or freeze.
byte strzlen(pointer str)
Calculates the length of a null-terminated string.
If the string is longer than 255 bytes, then the behaviour is undefined (might even crash).
sbyte strzcmp(pointer str1, pointer str2)
Compares two null-terminated strings. Returns 0 if equal, non-0 if not equal. If any of the strings is longer than 255 bytes, then the behaviour is undefined (might even crash).
void strzcopy(pointer dest, pointer src)
Copies the source null-terminated string into the destination buffer, including the string terminator. If the source string is longer than 255 bytes, then the behaviour is undefined (might even crash).
void strzpaste(pointer dest, pointer src)
Copies the source null-terminated string into the destination buffer, excluding the string terminator. If the source string is longer than 255 bytes, then the behaviour is undefined (might even crash).
word strz2word(pointer str)
Converts a null-terminated string to a number.
Sets errno.
void strzappend(pointer buffer, pointer str)
void strzappendchar(pointer buffer, byte char)
Modifies the given null-terminated buffer by appending a null-terminated string or a single character respectively.
scrstring
The scrstring module automatically imports the string and err modules.
It contains functions for handling strings in the screen encoding with the same semantics as the functions from the string module.
byte scrstrzlen(pointer str)
sbyte scrstrzcmp(pointer str1, pointer str2)
void scrstrzcopy(pointer dest, pointer src)
void scrstrzpaste(pointer dest, pointer src)
word scrstrz2word(pointer str)
void scrstrzappend(pointer buffer, pointer str)
void scrstrzappendchar(pointer buffer, byte char)
pstring
The pstring module automatically imports the err module.
It contains functions for handling length-prefixed strings in any 8-bit encoding.
byte pstrlen(pointer str)
sbyte pstrcmp(pointer str1, pointer str2)
void pstrcopy(pointer dest, pointer src)
void pstrpaste(pointer dest, pointer src)
void pstrappend(pointer buffer, pointer str)
void pstrappendchar(pointer buffer, byte char)
word pstr2word(pointer str)
Converts a length-prefixed string to a number. Uses the default encoding.
Sets errno.
word pscrstr2word(pointer str)
Converts a length-prefixed string to a number. Uses the screen encoding.
Sets errno.
