Translates between C language strings and their external representations.
C Library (libc.a)
The xdr_string subroutine is a filter primitive that translates between C language strings and their corresponding external representations. Externally, strings are represented as sequences of ASCII characters, while internally, they are represented with character pointers.
Item | Description |
---|---|
xdrs | Points to the eXternal Data Representation (XDR) stream handle. |
sp | Specifies the address of the pointer to the string. |
maxsize | Specifies the maximum length of the string allowed during encoding or decoding. This value is set in a protocol. For example, if a protocol specifies that a file name cannot be longer than 255 characters, then a string cannot exceed 255 characters. |
Upon successful completion, this subroutine returns a value of 1. If unsuccessful, it returns a value of 0.
