The list of executable program creation services consists of subroutines that support a group of commands. These commands and subroutines allow you to create, compile, and work with files in order to make your programs run.
| _end, _text, _edata | Define the last location of a program |
| confstr | Determines the current value of a specified system variable defined as a string |
| getopt | Gets flag letters from the argument vector |
| ldopen, ldaopen | Open a common object file |
| ldclose, ldaclose | Close a common object file |
| ldahread | Reads the archive header of a member of an archive file |
| ldfhread | Reads the file header of a common object file |
| ldlread, ldlinit, ldlitem | Read and manipulate line number entries of a common object file function |
| ldshread, ldnshread | Read a section header of a common object file |
| ldtbread | Reads a symbol table entry of a common object file |
| ldgetname | Retrieves a symbol name from a symbol table entry or from the string table |
| ldlseek, ldnseek | Seek to line number entries of a section of a common object file |
| ldohseek | Seek to the optional file header of a common object file |
| ldrseek, ldnrseek | Seek to the relocation information for a section of a common object file |
| ldsseek, ldnsseek | Seek to a section of a common object file |
| ldtbseek | Seeks to the symbol table of a common object file |
| ldtbindex | Returns the index of a particular common object file symbol table entry |
| load | Loads and binds an object module into the current process |
| unload | Unloads an object file |
| loadbind | Provides specific runtime resolution of a module's deferred symbols |
| loadquery | Returns error information from the load subroutine or the exec subroutine. Also provides a list of object files loaded for the current process |
| monitor | Starts and stops execution profiling |
| nlist | Gets entries from a name list |
| regcmp, regex | Compile and matche regular-expression patterns |
| setjmp, longjmp | Store a location |
| sgetl, sputl | Accesses long numeric data in a machine-independent fashion |
| sysconf | Determines the current value of a specified system limit or option |
