66 functions are the reentrant equivalents of, respectively,
70 .BR getrpcbynumber (3).
71 They differ in the way that the
73 structure is returned,
74 and in the function calling signature and return value.
75 This manual page describes just the differences from
76 the nonreentrant functions.
78 Instead of returning a pointer to a statically allocated
80 structure as the function result,
81 these functions copy the structure into the location pointed to by
86 array is used to store the string fields pointed to by the returned
89 (The nonreentrant functions allocate these strings in static storage.)
90 The size of this array is specified in
94 is too small, the call fails with the error
96 and the caller must try again with a larger buffer.
97 (A buffer of length 1024 bytes should be sufficient for most applications.)
98 .\" I can find no information on the required/recommended buffer size;
99 .\" the nonreentrant functions use a 1024 byte buffer -- mtk.
101 If the function call successfully obtains an RPC record, then
109 On success, these functions return 0.
110 On error, they return one of the positive error numbers listed in ERRORS.
112 On error, record not found
