Replace a marker with a character string.
None.
VARIABLE I/O DESCRIPTION -------- --- -------------------------------------------------- in I Input string. marker I Marker to be replaced. value I Replacement value. lenout I Available space in output string. out O Output string.
in is a character string. marker is character string indicating where a substring replacement is to be made. The first occurrence of marker in the input string is to be replaced by value. Leading and trailing blanks in marker are NOT significant. In particular, no substitution is performed if marker is blank. value is a replacement character string. Leading and trailing blanks in value are NOT significant: the portion of value that is substituted for marker extends from its first non-blank character to its last non-blank character. However, if value is blank or empty, a single blank is substituted for the first occurrence of marker. lenout is the allowed length of the output string. This length must large enough to hold the output string plus the terminator. If the output string is expected to have x characters, lenout should be at least x + 1.
out is the string obtained by substituting value (leading and trailing blanks excepted) for the first occurrence of marker in the input string. out and in must be identical or disjoint.
None.
This is one of a family of related routines for inserting values into strings. They are typically to construct messages that are partly fixed, and partly determined at run time. For example, a message like "Fifty-one pictures were found in directory [USER.DATA]." might be constructed from the fixed string "#1 pictures were found in directory #2." by the calls #include "SpiceUsr.h" . . . #define LENOUT 81 . . . repmct_c ( string, "#1", 51, 'c', LENOUT, string ); repmc_c ( string, "#2", "[USER.DATA]", LENOUT, string ); which substitute the cardinal text "Fifty-one" and the character string "[USER.DATA]" for the markers "#1" and "#2" respectively. The complete list of routines is shown below. repmc_c ( Replace marker with character string value ) repmd_c ( Replace marker with double precision value ) repmf_c ( Replace marker with formatted d.p. value ) repmi_c ( Replace marker with integer value ) repmct_c ( Replace marker with cardinal text) repmot_c ( Replace marker with ordinal text )
1. Let marker == "#" in == "Invalid operation value. The value was: <#>." Then following the call, #include "SpiceUsr.h" . . . #define LENOUT 201 . . . repmc_c ( in, "#", "append", LENOUT, in ) in is "Invalid operation value. The value was: <append>." 2. Let marker == " XX " in == "A syntax error occurred. The token XX was not " "recognized. Did you mean to say XX?" Then following the call, #include "SpiceUsr.h" . . . #define LENOUT 201 . . . repmc_c ( in, " XX ", " FND ", LENOUT, out ); out is "A syntax error occurred. The token FND was not " "recognized. Did you mean to say XX?" Making the additional call repmc_c ( out, " XX ", " found ", LENOUT, out ); yields the string "A syntax error occurred. The token FND was not recognized. Did you mean to say found?" 3. Let marker == "&" num == 23 chance == "fair" score == 4.665 Then following the sequence of calls, #include "SpiceUsr.h" . . . #define LENOUT 201 . . . repmi_c ( "There are & routines that have a " "& chance of meeting your needs. " "The maximum score was &.", marker, num, LENOUT, msg ); repmc_c ( msg, marker, chance, LENOUT, msg ); repmf_c ( msg, marker, score, 4, 'f', LENOUT, msg ); msg is "There are 23 routines that have a fair chance of " "meeting your needs. The maximum score was 4.665."
None.
1) If either the input or output string pointers are null, the error SPICE(NULLPOINTER) is signaled. 2) If the marker string is blank or empty, this routine leaves the input string unchanged, except that trailing blanks will be trimmed. This case is not considered an error. 3) If the output string is too short to accommodate a terminating null character, the error SPICE(STRINGTOOSHORT) is signaled. 4) If out does not have sufficient length to accommodate the result of the substitution, the result will be truncated on the right. 5) If value is blank or empty, a single blank is substituted for the first occurrence of marker.
None.
