CHKOBJ allows you to check if the file exists, and also allows you to optionally check if you have authority to use it. For the IFS we use access() API. Access() can be used to check two things: whether the file exists, and whether it's accessible for reading, writing or execution. Template Cv Yang Menarik. The C-language prototype for the access() API looks like this: int access(const char *path, int amode); Here is how we define the prototype in RPGLE daccess PR 10I 0 extproc('access') dpathptr1 * value dmode1 10I 0 value The access API returns an integer which can either be 0 if the file is accessible otherwise -1. The definition of the first parameter specifies “a pointer to the null-terminated path name.” In RPG, we are used to fixed-length strings (for example, we predefine the maximum length of character fields), but in C, the length of a string is indeterminate, and the length is based on what the content of the string is.

C strings are terminated with a null value to indicate the end of the string, which you must take into account when you call C functions from RPG. Faststone Photo Resizer 3 0 Keygen Rar. Use OPTIONS(*STRING) on the definition of the parameter in the prototype, and use the%STR built in function to retrieve a string returned from a C function.

The definition of the second parameter reads a lot more complicated then it actually is. A lot of the APIs written in C use a method of setting bits in a byte to indicate certain requirements. The different permutation and combination of bits are defined as named constants. The documentation tells you that the values you can specify for the second parameter are represented by one of the named constants (F_OK, R_OK, W_OK or X_OK), which are defined in the member unistd.h.
