Input file lines length.
Maximum PellesC input line lenght is 4095 chars.
As previously pointed out by Timo, the limits of translation, specify the length of
logical lines, see
ISO/IEC 9899:2017 ยง5.2.4.1 Translation limits (but also C99-C11), as follow:
The implementation shall be able to translate and execute at least one program that contains at least
one instance of every one of the following limits:
- 127 nesting levels of blocks
- 63 nesting levels of conditional inclusion
- 12 pointer, array, and function declarators (in any combinations) modifying an arithmetic, structure, union, or void type in a declaration
- 63 nesting levels of parenthesized declarators within a full declarator
- 63 nesting levels of parenthesized expressions within a full expression
- 63 significant initial characters in an internal identifier or a macro name(each universal character name or extended source character is considered a single character)
- 31 significant initial characters in an external identifier (each universal character name specifying a short identifier of 0000FFFF or less is considered 6 characters, each universal character name specifying a short identifier of 00010000 or more is considered 10 characters, and each extended source character is considered the same number of characters as the corresponding universal character name, if any)
- 4095 external identifiers in one translation unit
- 511 identifiers with block scope declared in one block
- 4095 macro identifiers simultaneously defined in one preprocessing translation unit
- 127 parameters in one function definition
- 127 arguments in one function call
- 127 parameters in one macro definition
- 127 arguments in one macro invocation
- 4095 characters in a logical source line
- 4095 characters in a string literal (after concatenation)
- 65535 bytes in an object (in a hosted environment only)
- 15 nesting levels for #included files
- 1023 case labels for a switch statement (excluding those for any nested switch statements)
- 1023 members in a single structure or union
- 1023 enumeration constants in a single enumeration
- 63 levels of nested structure or union definitions in a single struct-declaration-list
You should check that your source is compliant with each one of the limits above, if your code can compile with a different compiler it should be considered a custom extension of such a compiler, and then
the code not portable.
